Question:
The Op-Amp circuit shown below is a (an)
The Op-Amp circuit shown below is a (an)
Show Hint
A diode in feedback of an Op-Amp results in a logarithmic amplifier.
Updated On: May 23, 2025
- Anti-log amplifier
- Logarithmic amplifier
- Clamping circuit
- Clipping circuit
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
The given circuit uses a diode in the feedback path of the Op-Amp.
Such a configuration is known to produce a logarithmic output, since the current through the diode is exponential w.r.t. voltage.
