摘　　要：为了拓展称重传感器的工作频带,把电荷转移器件(CTD)用于其动态补偿器的设计中,设计出具有频率特性可调节的动态补偿器。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,理论分析和实验表明了所设计的动态补偿器是有效的,提高了补偿器的通用性和实时性,对补偿器的实用化有重要意义。In order to extend the weighing sensor work frequency band, a new adaptive dynamic compensator is designed based on charge transfer devices （CTD）, whose frequency characteristics is adjustable. The compensating principle and circuit design as well as the key technology and the corresponding solution are discussed. The theoretical analysis and experiment result show that the universality and real time of compensation devices are improved. The design is of important value for practicality of the dynamic compensation device of weighing sensor.
