鉴相器及其集成

Phase Detector and Its Integration

本文简述了鉴相器的作用、功能和分类；详述了理想乘法器和吉尔伯特乘法器单元电路的工作原理及其鉴相特性；介绍了几种可资采用的集成鉴相器的外围电路、特点、主要技术特性及目前的研制动向。

A brief introduction is made about the phase detector.its applications,functions and classifica- tion. The principle of operation of an ideal multiplier and Gilbert multiplier unit circuit is described in detail, together with its phase detection characteristies. Peripheral circuits of some applicable phase detector IC’s.their characteristics and specifications are Dresented.
