摘　　要：研制了一种以电荷转移器件 (CTD)为核心 ,具有频率特性可随意调节的压电传感器频率特性补偿器。论述了补偿原理、电路设计及其技术难点和相应的解决方法。理论分析与实验表明了该补偿器的有效性、实用性、先进性。A compensator of frequency characteristic of piezoelectric sensor is presented.This compensator has the adjustable frequency characteristic arbitrarily based on charge transfer devices (CTD). The compensating principle and circuit design as well as the key technologies and the corresponding solution methods are discussed. The theoretical analysis and experiments demonstrate that the compensator is very effective on extending the work frequency band of sensor,as well as advanced and practical.
