摘　　要：本文通过对传统相敏解调器原理的分析，提出了一种基于同步相控原理的应用于陀螺平台稳定回路中的相敏解调器。该电路采用独特的电路拓扑结构，解决了传统电路体积大、电路复杂等问题。针对电路的输出零位电压，通过合理的参数设计和先进的薄膜工艺，将零位电压降低了一个数量级，极大地改善了电路零位特性，对提高整机性能具有重要的意义。Based 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 parame- ters and thin - film technology. It greatly improves the zero position characteristics of circuit, and is of great significance to im- prove the performance of the whole machine.
