Abstract
In some embodiments, a microphone system includes a multi-bit delta-sigma modulator configured to be coupled to a microphone and configured to covert an output of the microphone into a first digital signal with a multi-bit resolution at a first output of the multi-bit delta-sigma modulator. The microphone system also includes a digital noise shaper coupled to the first output of the multi-bit delta-sigma modulator, and configured to convert a multi-bit digital input of the digital noise shaper into a one-bit digital signal.
