摘要： A digital microphone comprises a ΔΣ modulator. The ΔΣ modulator has a resonator including a membrane which vibrates by receiving a sound wave and a wiring pattern disposed opposite to the membrane, an oscillator, including the resonator, for outputting an FM signal according to the vibration of the membrane, and a one-bit quantizer for outputting a one-bit quantized signal by sampling the FM signal with a high-frequency clock.

摘要翻译： 数字麦克风包括DeltaSigma调制器。 DeltaSigma调制器具有包括通过接收声波而振动的膜和与膜相对设置的布线图案的振荡器，包括谐振器的振荡器，用于根据膜的振动输出FM信号， 用于通过用高频时钟采样FM信号来输出一位量化信号。
