Adaptive bias the future of the Class A amplifier. A classs A brief tutorial Introduction An audio power amplifier is designed to drive loudspeakers. To do this it needs to deliver lots of volts and lots of current, usually simultaneously, to a low impedance, Solution:- The ac power in class A-operation, P 0 is given by the relation, 0. 2 VI CEQ CQ P Where V CEQ and I CQ are voltage across collector – emitter of transistor at operating point.

So far, we have seen two types of class A power amplifiers. The main problems that should be dealt with are low power output and efficiency. It is possible to obtain greater power output and efficiency than that of the Class A amplifier by using a combinational transistor pair called as … Notes: When output power is above the class-A region the amplifier operates in class-B, once output power reduces back into the class-A region then the amplifier resumes class-A operation. If the long term average power output is too high and internal temperatures exceed the normal operating range then the amplifier will operate in class-B until normal operating temperature is reached

The distortion produced by a typical solid-state Class-B power amplifier is shown to consist of eight mechanisms, all of which may co- exist and whose distortion products overlap to give a complex result. The first power supply is of lower power and within this region we run in pure Class A, which has no crossover distortion. As the secondary supply is only used As the secondary supply is only used when required, extreme levels of power are possible because very little energy is wasted in the amplifier as heat when it is not being used.

PDF In literature, it is widely accepted that the design of Class-E Power Amplifier (PA) with finite dc feed inductance requires a long iterative solution procedure. To avoid such iterative The first power supply is of lower power and within this region we run in pure Class A, which has no crossover distortion. As the secondary supply is only used As the secondary supply is only used when required, extreme levels of power are possible because very little energy is wasted in the amplifier as heat when it is not being used.
