It features a typical though substantially simplified design as found in modern amplifiers, with a class-AB push—pull output stage, and uses some overall negative feedback. In practice, amplifier power gain depends on the source and load impedancesas well as the inherent voltage and current gain.

Traveling wave tube amplifiers TWTAs are used for high power amplification at low microwave frequencies. They typically can amplify across a broad spectrum of frequencies; however, they are usually not as tunable as klystrons.

Klystrons are specialized linear-beam vacuum-devices, designed to provide high power, widely tunable amplification of millimetre and sub-millimetre waves.

Klystrons are designed for large scale operations and despite having a narrower bandwidth than TWTAs, they have the advantage of coherently amplifying a reference signal so its output may be precisely controlled in amplitude, frequency and phase.

Instrument amplifiers are a range of audio power amplifiers used to increase the sound level of musical instruments, for example guitars, during performances.

One set of classifications for amplifiers is based on which device terminal is common to both the input and the output circuit.

In the case of bipolar junction transistors , the three classes are common emitter, common base, and common collector.

For field-effect transistors , the corresponding configurations are common source, common gate, and common drain; for vacuum tubes , common cathode, common grid, and common plate.

The common emitter or common source, common cathode, etc. The common collector arrangement applies the input voltage between base and collector, and to take the output voltage between emitter and collector.

This causes negative feedback, and the output voltage tends to follow the input voltage. This arrangement is also used as the input presents a high impedance and does not load the signal source, though the voltage amplification is less than one.

The common-collector circuit is, therefore, better known as an emitter follower, source follower, or cathode follower. The input impedance of a unilateral amplifier is independent of load, and output impedance is independent of signal source impedance.

An amplifier that uses feedback to connect part of the output back to the input is a bilateral amplifier. Bilateral amplifier input impedance depends on the load, and output impedance on the signal source impedance.

All amplifiers are bilateral to some degree; however they may often be modeled as unilateral under operating conditions where feedback is small enough to neglect for most purposes, simplifying analysis see the common base article for an example.

Another way to classify amplifiers is by the phase relationship of the input signal to the output signal. An emitter follower is a type of non-inverting amplifier, indicating that the signal at the emitter of a transistor is following that is, matching with unity gain but perhaps an offset the input signal.

Voltage follower is also non inverting type of amplifier having unity gain. Other amplifiers may be classified by their function or output characteristics.

These functional descriptions usually apply to complete amplifier systems or sub-systems and rarely to individual stages. Amplifiers are sometimes classified by the coupling method of the signal at the input, output, or between stages.

Different types of these include:. Depending on the frequency range and other properties amplifiers are designed according to different principles.

Frequency ranges down to DC are only used when this property is needed. Amplifiers for direct current signals are vulnerable to minor variations in the properties of components with time.

Depending on the frequency range specified different design principles must be used. Up to the MHz range only "discrete" properties need be considered; e.

For example, a specified length and width of a PCB trace can be used as a selective or impedance-matching entity. Above a few hundred MHz, it gets difficult to use discrete elements, especially inductors.

In most cases, PCB traces of very closely defined shapes are used instead stripline techniques. The power amplifier classes are based on the proportion of each input cycle conduction angle during which an amplifying device passes current.

The angle of flow is closely related to the amplifier power efficiency. The practical amplifier circuit to the right could be the basis for a moderate-power audio amplifier.

It features a typical though substantially simplified design as found in modern amplifiers, with a class-AB push—pull output stage, and uses some overall negative feedback.

Bipolar transistors are shown, but this design would also be realizable with FETs or valves. The input signal is coupled through capacitor C1 to the base of transistor Q1.

The capacitor allows the AC signal to pass, but blocks the DC bias voltage established by resistors R1 and R2 so that any preceding circuit is not affected by it.

Q1 and Q2 form a differential amplifier an amplifier that multiplies the difference between two inputs by some constant , in an arrangement known as a long-tailed pair.

This arrangement is used to conveniently allow the use of negative feedback, which is fed from the output to Q2 via R7 and R8. The negative feedback into the difference amplifier allows the amplifier to compare the input to the actual output.

The amplified signal from Q1 is directly fed to the second stage, Q3, which is a common emitter stage that provides further amplification of the signal and the DC bias for the output stages, Q4 and Q5.

R6 provides the load for Q3 a better design would probably use some form of active load here, such as a constant-current sink.

So far, all of the amplifier is operating in class A. The output pair are arranged in class-AB push—pull, also called a complementary pair. They provide the majority of the current amplification while consuming low quiescent current and directly drive the load, connected via DC-blocking capacitor C2.

The diodes D1 and D2 provide a small amount of constant voltage bias for the output pair, just biasing them into the conducting state so that crossover distortion is minimized.

That is, the diodes push the output stage firmly into class-AB mode assuming that the base-emitter drop of the output transistors is reduced by heat dissipation.

This design is simple, but a good basis for a practical design because it automatically stabilises its operating point, since feedback internally operates from DC up through the audio range and beyond.

Further circuit elements would probably be found in a real design that would roll-off the frequency response above the needed range to prevent the possibility of unwanted oscillation.

A common solution to help stabilise the output devices is to include some emitter resistors, typically one ohm or so.

Any real amplifier is an imperfect realization of an ideal amplifier. An important limitation of a real amplifier is that the output it generates is ultimately limited by the power available from the power supply.

An amplifier saturates and clips the output if the input signal becomes too large for the amplifier to reproduce or exceeds operational limits for the device.

The power supply may influence the output, so must be considered in the design. The power output from an amplifier cannot exceed its input power.

The amplifier circuit has an "open loop" performance. This is described by various parameters gain, slew rate , output impedance , distortion , bandwidth , signal-to-noise ratio , etc.

Many modern amplifiers use negative feedback techniques to hold the gain at the desired value and reduce distortion. Negative loop feedback has the intended effect of lowering the output impedance and thereby increasing electrical damping of loudspeaker motion at and near the resonance frequency of the speaker.

When assessing rated amplifier power output, it is useful to consider the applied load, the signal type e. In high-powered audio applications that require long cables to the load e.

This avoids long runs of heavy speaker cables. To prevent instability or overheating requires care to ensure solid state amplifiers are adequately loaded.

Most have a rated minimum load impedance. All amplifiers generate heat through electrical losses. The amplifier must dissipate this heat via convection or forced air cooling.

Heat can damage or reduce electronic component service life. Designers and installers must also consider heating effects on adjacent equipment.

Different power supply types result in many different methods of bias. Bias is a technique by which active devices are set to operate in a particular region, or by which the DC component of the output signal is set to the midpoint between the maximum voltages available from the power supply.

Most amplifiers use several devices at each stage; they are typically matched in specifications except for polarity. Matched inverted polarity devices are called complementary pairs.

Class-A amplifiers generally use only one device, unless the power supply is set to provide both positive and negative voltages, in which case a dual device symmetrical design may be used.

Class-C amplifiers, by definition, use a single polarity supply. Amplifiers often have multiple stages in cascade to increase gain. Each stage of these designs may be a different type of amp to suit the needs of that stage.

For instance, the first stage might be a class-A stage, feeding a class-AB push—pull second stage, which then drives a class-G final output stage, taking advantage of the strengths of each type, while minimizing their weaknesses.

Return policy Warranty at digitec. Mail delivery Expected delivery time: In practice, amplifier power gain depends on the source and load impedances , as well as the inherent voltage and current gain.

A radio frequency RF amplifier design typically optimizes impedances for power transfer, while audio and instrumentation amplifier designs normally optimize input and output impedance for least loading and highest signal integrity.

Efficiency considerations lead to the various classes of power amplifier based on the biasing of the output transistors or tubes: Audio power amplifiers are typically used to drive loudspeakers.

They will often have two output channels and deliver equal power to each. An RF power amplifier is found in radio transmitter final stages. A Servo motor controller: An operational amplifier is an amplifier circuit which typically has very high open loop gain and differential inputs.

Op amps have become very widely used as standardized "gain blocks" in circuits due to their versatility; their gain, bandwidth and other characteristics can be controlled by feedback through an external circuit.

Though the term today commonly applies to integrated circuits, the original operational amplifier design used valves, and later designs used discrete transistor circuits.

A fully differential amplifier is similar to the operational amplifier, but also has differential outputs.

These use balanced transmission lines to separate individual single stage amplifiers, the outputs of which are summed by the same transmission line.

The transmission line is a balanced type with the input at one end and on one side only of the balanced transmission line and the output at the opposite end is also the opposite side of the balanced transmission line.

The gain of each stage adds linearly to the output rather than multiplies one on the other as in a cascade configuration. This allows a higher bandwidth to be achieved than could otherwise be realised even with the same gain stage elements.

These nonlinear amplifiers have much higher efficiencies than linear amps, and are used where the power saving justifies the extra complexity.

Class-D amplifiers are the main example of this type of amplification. Compared to other types of amplifiers, this "negative resistance amplifier" will only require a tiny amount of power to achieve very high gain, maintaining a good noise figure at the same time.

Certain requirements for step response and overshoot are necessary for an acceptable TV image. Traveling wave tube amplifiers TWTAs are used for high power amplification at low microwave frequencies.

They typically can amplify across a broad spectrum of frequencies; however, they are usually not as tunable as klystrons. Klystrons are specialized linear-beam vacuum-devices, designed to provide high power, widely tunable amplification of millimetre and sub-millimetre waves.
