声表面波相关叉指换能器的半物理仿真
Semi-physical Simulation of SAW CIDTs
摘要
Abstract
In order to test the correlation properties of the physical CIDT devices more convenient-ly and flexibly,a semi-physical simulation method of the SAW CIDT was proposed based on ADS software.This method abstracted the physic devices by their S-parameters from actual tests and estab-lished the virtual excitation signal generating circuits in the ADS.By using the transient simulation function of the ADS,the different responses of the physical devices to the various excitation signals were studied.Compared with the theoretical simulation by the MATLAB and the experimental results by the reader,the semi-physical simulation by the ADS was confirmed to be feasible to study the cor-relation properties of the CIDTs.关键词
