Abstract: This article presents a lumped-parameter model (LPM) providing a deeper understanding of the compliant backplate in capacitive micro-electromechanical systems (MEMS) microphones. Some previous models simplify the backplate as stationary, whereas others treat it as vibrating.… read more here.
