The class AB amplifier is built using a blend f characteristics from class A and Class B circuit designs, hence the name Class AB. Although Class AB design also works with a pair of complementary BJTs, the output stage ensures that the biasing of the power BJTs are controlled close the the cut-off threshold, in the absence of an input signal. The main difference with the Class A is that Class B amplifiers have a conduction angle of 180°. This implies that only half of the input signal is processed in order to realize the amplification process.
