Precision half wave rectifier

00:58:25

Input=500mv,50hz Ac to all circuit.
Using conventional rectifier circuit it is not possible to rectify Ac voltage below 0.6v because the minimum voltage required to forward bias a silicon diode is 0.6v.
But with precision rectifiers we can rectify signal of very small range, even of mv.
The op-amp circuit(both) is precision rectifier, while the 3rd one is our conventional rectifier circuit. Observe the output waveform of each circuit.
