EXPERIMENT-7
Aim:
Design of class AB Amplifier using Keysight
ADS.
Theory:
To overcome crossover distortion, the biasing is adjusted
to just overcome the VBE of the ransistors. In class AB operation, the
push-pull stages are biased into slight conduction, even when no input signal
is present. This can be done with a voltage-divider and diode arrangement, as
shown
Class AB
amplifier:
Using equal values of R1 and R2 the positive and negative
supply voltages forces the voltage at point A
to equal 0 V and eliminates the need for an input coupling capacitor.
