The Optimization Of The X47 Phase-detector IC

The X47 phase-detector is an analog integrated circuit produced by the 24th Institute of the Information Industry Department. The main function of X47 phase-detector is to detect the difference of phases of its two input signals. But it抪erformance can not be analyzed by directly using the OrCAD/PSpice9?----a world-wide well known general purpose simulation software,and all circuits and systems using this kind of phase detector can not be directly simulated by OrCAD/PSpice9 either. This paper solves the two problems firstly, and then analyzes the performance of X47 phase-detector with the OrCADIPSpice9抯 function of performance analysis, gives the theoretical analysis of it抯 working principle, optimizes it with OrCAD/PSpice9 software.Through all the works above,this paper summarizes the technique to analyse the phase-detector type circuits with OrCAD/PSpice9 software, especially it抯 function of parameter sweep and performance analysis; summes up the ways and means to optimize phase-detector type circuits with OrCADIPSpice9抯 optimizer module. All this technique and means can be used as a guide for analyzing and optimizing phase-detector type circuits, and the technique to use performance analysis function can be used for designing all kinds of circuits.
