Abstract
A dual stage adaptive peak detect circuit includes a fast peak detector that detects the trends in the magnitude of the incoming signal and an adaptable peak detector that accurately follows the peak of the signal. A difference circuit detects the voltage difference between the outputs of the fast peak detector and the adaptable peak detector. A voltage-to-current converter feeds back the current-converted difference voltage to the adaptable peak detector to adjust its peak detection charge current. The dual stage adaptive peak detector of the present invention is thus capable of accurately following the peak of an incoming signal with varying amplitudes.
