The NPN transistor (emitter follower) is sourcing Class A amplifier design produces a good linear amplifier, but most of the power produced by the amplifier goes wastage in the form of heat. Since the transistors in Class A amplifier, are forward biased all the time, few current will flow through them even though there is no input signal and this is the main reason for its poor efficiency.

Class B and AB amplifiers are used as output Block diagram of an amplifier. Amplifier Biasing. For amplifiers to operate properly, they must be … Class AB Amplifier Radio Frequencies (RF) Class C Amplifier VHF, UHF and SHF Frequencies Generally, amplifiers can be sub-divided into two distinct types depending upon their power or voltage gain. One type is called the Small Signal Amplifier which include pre-amplifiers, instrumentation amplifiers etc.

October 26, 2016. Class AB Circuit Operation – VTC cont. i P i N =I Q The constant base voltage condition 2 For example let I Q = 1 mA and i N = 10 mA. i P= I Q 2 i N = 1⋅10−6 10⋅10−3 =0.1mA= 1 100 i N The Class AB circuit, over most of its input signal range, operates as if either the Q N or Q P transistor is conducting and the Q P or Q N transistor Apr 9, 2017 - Discrete Class AB Transistor Audio Power Amplifier Circuit Diagram This is a class AB transistor power amplifier. It is a simple amplifier to build, uses Class A Amplifier Circuit Working and Applications. Class AB power amplifier; the amplifier relatively free from noise by making the signal waveform out of the region between 0v to 0.6v where the transistor’s input characteristic is non-linear. Push-pull Class B amplifiers made with BJTs can be constructed using a NPN transistor for one element and a PNP transistor for the other element or with two of the same type of transistor.
