peak detector circuit -patent
Hi,
(sorry to repost, forgot the attachment)
An important part of a current project of mine is a peak detector circuit which takes a base audio signal from say a microphone (~50mV), amplifies it and squares it. I have attached the schematic of this circuit.
(The first stage is a non-inverting amplifier, the second stage is a second order lowpass
Butterworth filter, stage three is a peak rectifier and the last stage is a bistable
multivibrator)
Is there any package available that contains this circuit in just one chip?
considering that this circuit should be quite common among other audio applications, there must be such a chip!
Any help would be great!
Thanks
