Capacitive (condenser) MEMS microphones have been developed using various design and fabrication techniques to improve performance. Mechanical sensitivity of a condenser MEMS microphone can be increased by reducing the residual stress of the diaphragm using several design approaches including corrugated diaphra...
This dissertation demonstrates the feasibility of three novel low-power and low-noise schemes for the readout interfaces of MEMS Capacitive Microphones (MCM) by presenting their detailed design descriptions and measurement results as application-specific ICs (ASIC) in CMOS technology developed to exploit...

As so far, a micro-electro-mechanical-system (MEMS) Microphone is widely used and has good performance. FIG.1is a schematic cross-sectional view of a microphone in the related art. The microphone10includes a backplate11and a diaphragm12, which is opposite to the backplate11and connected to...
In an embodiment, C1is between about 0.1 pF to about 10 pF, while C2is between about 1 pF and about 11 pF, hence, the gain of stage304may be between about 1 and about 11. Such values may be used, for example, with MEMS microphones are capacitive sensors having a capacitance Cmic ...
