Advantages of Class A Amplifiers. The advantages of Class A power amplifier are as follows −. The current flows for complete input cycle; It can amplify small signals; The output is same as input; No distortion is present; Disadvantages of Class A Amplifiers. The advantages of Class A power amplifier are as follows −. Low power output; Low collector efficiency. DC biasing and AC analysis of small signal bipolar and FET amplifiers along with class A and B large signal analysis. For equipment, each lab station should include a dual adjustable DC power supply, a dual trace oscilloscope, a function generator and a quality DMM. Some exercises also make use of a distortion. The amplifier is said to be class A power amplifier if the q point and the input signal are selected such that the output signal is obtained for a full input cycle. For.
