CMT: An Equivalent Circuit Modeling Tool for Ultrasonic Transducer  
BibTex | RIS | RefWorks Download
The equivalent circuit modeling of sensor can simplify the sensing problem as a pure electronics problem. As one kind of widely used sensor, there are also numerous equivalent circuit models for the ultrasonic transducer. However, the parameters of equivalent circuit of transducer are inconvenient for a common engineer to calculate, since so many variables, constants and formulae are involved in. Motivated by this, a toolkit named CMT is proposed. When given the details about the transducer in use and the requirement about the equivalent circuit, this tool will generate the SPICE file for the circuit. Such a SPICE file can be subsequently used in a circuit simulating software, for test of transducer properties and for the development of sensing system. For a better use, some optimizations are adopted, to minimize the working load of user in data management, and to speedup the calculation of the circuit parameters.
