Inter Digital Transducer Modelling through Mason Equivalent Circuit Model Design and Simulation

The frequency reliance of inter-digital transducer is analyzed with the help of MASON's Equivalent circuit which is based on Smith's Equivalent circuit which is further based on Foster's Network. An inter-digital transducer has been demonstratedas a RLC network. The circuit is simulated by Simulation program with Integrated Circuit Emphasis (HSPICE), a well-liked electronic path simulator. The acoustic wave devices arc not suitable to simulation through circuit simulator. In this paper, an electrical model of Mason's Equivalentelectricalcircuit for an inter-digital transducer (IDT) is projected which is well-suited with a broadlycast-off universal resolution circuit simulator SPICE built-in out with the proficiency to simulate the negative capacitances and inductances. The investigationis done to prove the straightforwardness of establishing the frequency and time domain physical characteristics of the IDT and flexibility to simulate the IDT laterally with other peripheral circuit elements. Sensors with high Q for resonance provide a better stability.
