A Switched Capacitor (SC) interface for a capacitive MEMS microphone is described in this paper. By properly switching the sensor, parasitic insensitive ac-coupling readout is directly performed without the need of a large bias resistor.

Abstract
A Switched Capacitor (SC) interface for a capacitive MEMS microphone is described in this paper. By properly switching the sensor, parasitic insensitive ac-coupling readout is directly performed without the need of a large bias resistor. The SC readout-circuit offers the advantages of a differential- topology for a single-ended sensor without accurate capacitor matching techniques. © 2006 IEEE.
