Power amplifier presentation EEE 205 GUB

The document summarizes different classes of power amplifiers: Class A amplifiers conduct through the full 360 degrees of the input signal with the Q-point set in the middle of the load line. Class B amplifiers conduct through 180 degrees of the input with the Q-point at 0V. Class AB is a compromise between A and B, conducting between 180-360 degrees with the Q-point between the midpoint and cutoff. Class C conducts less than 180 degrees with the Q-point below cutoff. Class D is biased for digital signals and has high efficiency.
