Design And Construction Of A Peak Detector Circuit

ABSTRACT

Peak Detector Circuit is used to find the peak amplitude in a rapidly changing waveform. Peak detectors are generally used in the sound measuring applications to find the maximum level of sound in a particular area or place, that helps in determining the maximum loudness level in that place.

This work is on op-amp based peak detector, used to remove the voltage drop across the diode. Whenever the applied input voltage signal is greater than the threshold voltage of the diode, the diode will get forward biased and acts as a closed switch. Here, the diode is connected in the feedback and hence the circuit works as a buffer circuit. So, whatever input is applied to the positive terminal of the op-amp will be received at the output terminal.
