A New Method to Improve the Simulation Of Piezoelectric Transducer Using PSPICE And Genetic Algorithms
Journal Title: International Journal on Computer Science and Engineering - Year 2011, Vol 3, Issue 4
Abstract
Piezoelectric transducer (SAW devices) is a very important device in industry but it is very difficult to simulate it using any circuit-simulation program. This paper proposes a practical method to simulate the Mason’s model of piezoelectric transducer directly with no approximation for different values of the model’s components using PSPICE. The paper also improves the simulated circuit component values using a Genetic Algorithms module. This optimization of the simulated circuit parameters minimizes the difference between the real output behavior of the piezoelectric transducer and the output of the simulated circuit using PSPICE. The paper also contrasts the new method with two other methods that simulate the Mason’s model of the piezoelectric transducer.
