ABSTRACT:
A signal detector whose output voltage approximates the true average to peak value of an applied signal of a generally arbitrary waveform employs current sources to regulate the charge-discharge duty cycle of an integrating storage device. The integrating storage device, such as an integrating capacitor, is employed in a high gain circuit with negative feedback to develop a signal representative of the peak level of the applied signal. The device approaches true peak detection over a wide dynamic and frequency operating range relative to known prior art at peak detection devices.
