A new peak detector circuit with changing-peak number and time detectors

Abstract

This paper presents a new peak detector circuit with changing-peak number and time detectors. For a conventional (OA) peak detector, the circuit can detect only the peak voltage. But, for the new proposed peak detector, it consists of an OA and a current-feedback opamp (CFA); it can detect not only the peak voltage, but also changing-peak number and time by means of an output pulse. Absolutely, the new proposed peak detector yields wider applications than the conventional one. The proposed peak detector is verified by the PSPICE program to ensure that it can operate as the theory.
