CROSS OVER DISTORTION

A normally used technique for the purpose of eliminating crossover distortion is by way of biasing the transistors so that they are on the point of conducting. With BJTs, this would mean the biasing them so that vBE is equal to 0.7 V when there is no signal. The very easy way to do all this is to making use of the 0.7 V voltage level drop across a forward-biased diode. In the circuit diagram shown below, current flows through the chain that contains R1, D1, D2 and R2.
