Design of Phase Sensitive Demodulator Used in the Stabilization Loop of Gyro Platform and Zero Control

AbstractBased on the analysis of the traditional Phase Sensitive Demodulator (PSD), this paper presents a PSD Used in the Stabilization Loop of Gyro Platform. This circuit adopts unique circuit topology, solved the problem of traditional circuit of large volume, complex circuit etc. The output zero voltage is reduced by an order of magnitude through reasonable designed of parameters and Thin-Film technology. It greatly improves the zero position characteristics of circuit, and is of great significance to improve the performance of the whole machine.
