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 ┬áis 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 …
