Question

Conisder a precision rectifier circuit shown in the figure below




The transfer characteristics curve of the circuit is given by

• A.
• B.
• C.
• D.

Answer 1

The correct option is B

The above circuit is a positive half - wave precision rectifier.

Case 1: If $V_{in}>0$, then diode will conduct thus, $V_{out}=V_{in}(\because$ the op-amp will work as a buffer.)

Case 2: If $V_{in}<0$, then diode will be OFF hence $V_{out}=0,$
