摘要/Abstract

摘要： 为方便、灵活地研究相关叉指换能器实物的相关性能，提出了一种基于ADS软件的可对声表面波相关叉指换能器性能进行验证的半物理仿真方法。该方法利用实际器件实测的S参数，在ADS中构建其物理抽象模型，并通过虚拟构建激励信号产生电路，利用ADS瞬态仿真功能，研究实际器件在不同激励信号下的响应，由此分析相关叉指换能器的相关性能。将半物理仿真结果分别与MATLAB理论仿真及阅读器实验结果进行对比，验证了该方法的可行性。

Abstract: In order to test the correlation properties of the physical CIDT devices more conveniently 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 established 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 correlation properties of the CIDTs.

Key words: surface acoustic wave(SAW), correlation inter-digital transducer(CIDT), semi-physical simulation, auto-correlation
