Figure 2. SEM image of MEMS microphone. Figure 3. Cross section of a MEMS microphone. Because the geometries are tightly controlled during the manufacturing process, the measured performance from microphone to microphone is highly repeatable. Another advantage of using MEMS technology to build microph...
The ASIC inside a MEMS microphoneuses a charge pump to place a fixed charge on the microphone membrane. The ASIC then measures the voltage variations caused when the capacitance between the membrane and the fixed backplate changes due to the motion of the membrane in response to sound waves. ...
