In figure below assume that the diode and op-amps are ideal. For an input Vin = sin ωt, the output voltage V0 is:
-
- full wave rectified with a peak value of 1
- full wave rectified with a peak value of – 1
- half wave rectified with a peak value of – 1
- half wave rectified with a peak value of ± 1
Correct Option: C
The op-amp (1) circuit represent precision half wave rectifier conducting for negative cycle at the inverting input, and op-amp (2) is a unity follower.
Hence alternative (C) is the correct choice.
