Abstract
A digital microphone includes a first modulation path having an input for receiving an analog input signal and an output for generating a first digital signal; a second modulation path having an input for receiving the analog input signal and an output for generating a second digital signal; a summing circuit having a first input for receiving the first digital signal, a second input for receiving the second digital signal, and an output for generating a digital calibration path signal; and a difference circuit having a first input for receiving the first digital signal, a second input for receiving the second digital signal, and an output for generating a digital signal path signal.
