摘要

This contribution reports the design, fabrication and characterization of a bulk acoustic mode resonator at VHF band using the polysilicon layer of a standard CMOS technology (AMS 0.35 mu m). The resonator is electrostatically actuated and capacitive transduced operating at 230 MHz. A discussion on frequency response enhancement with piezoresistive transduction is provided.
