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. Key words : piezoelectric sensor ; frequency characteristic ; compensator ; charge transfer devices (CTD)
