description An alternative sensing circuit for a micro-electro-mechanical system (MEMS) microphone and a sensing method thereof are provided. The sensing circuit reads out output signals of an MEMS electret microphone or an MEMS condenser microphone. In considering different operating requirements of the different MEMS microphones, for example, low power consumption for the MEMS electret condenser microphone or high sensitivity for the MEMS condenser microphone, the manner of using two kinds of MEMS microphone sensing components in one circuit can significantly increase the flexibility of using the MEMS microphone and can be applied to the application or design of a condenser sensing component.
