Abstract
A modular RC-active circuit is proposed in this paper to emulate the behavior of a fourth order transmission line, which is able to perform multimodal control of vibrations in piezo-electro-mechanical systems. The basic idea of this work is to consider the line as the cascade of basic sections and to design a RC-active circuit whose voltage signals emulate actualvoltages and currents of the section. The principal advantages of this approach, with respect to the straightforward synthesis of each inductor, are the saving of one amplifier for each section, the opportunity to connect the piezo-electric capacitance to high impedance nodes and the possibility to obtain a scheme very suitable for integration purposes. © 2005 IEEE.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
