Class A power amplifier is one of the simplest types of power amplifier have high fidelity and totally immune to crossover distortion. In the standard common emitter circuit configuration, class A amplifier uses the switching transistor.  The transistor is always turned ON so that the output current flows for the entire cycle of the input waveform. To control the high load current, class A amplifier may use a single power transistor or a pair of a transistor connected together. In our previous article, we explain power amplifier circuit,  semiconductors, diodes, rectifiers in detail. Here we are going to explain Class A Read More …

Power Amplifier Circuit, Classes and its Characteristics

A Power amplifier is a type of amplifier used to increase the amplitude of the signal and makes it stronger than the given input signal. It is the most demandable electronic device in the eyes of professional because it comes in various forms and used in a number of circuits. The main operating characteristics of an ideal amplifier is power output, signal gain, efficiency and linearity but normally there is always remain some trade-off between these characteristics. As we know not all amplifiers provide an accurate output, and there is always cost factor to consider. In our previous article, we Read More …
