Equivalent Circuits for Resonators and Transducers Driven Piezoelectrically.

摘要

A powerful motivation for using equivalent circuits to characterize piezoelectric devices is that the using equipment is often itself completely electrical in nature. The whole ensemble thus becomes subject to analysis or synthesis from a single perspective, i.e., network theory. In this report are described a brief history of circuit equivalents through the Mason circuit, followed by a presentation of newer descriptions of piezoelectrically vibrating structures, specifically, analog networks and KLM circuits.
