Power Amplifier Circuit, Classes and its Characteristics

Power amplifier image

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 …
