An analog signal processing circuit of a microphone includes a bias circuit including a first sub-circuit which receives a signal from the microphone to output a first signal and a second sub-circuit which receives a reference voltage to output a second signal. A fully differential circuit receives the first signal and the second signal to output a fully differential signal. Each of the first sub-circuit and the second sub-circuit includes a bias sub-circuit to apply a bias voltage.
