ABSTRACT:
An amplification circuit is provided for the signal output from a microphone in which the signal is amplified by a differential structure amplifier. The circuit includes the pull-up voltage, which initializes the operating state of the microphone, being coupled to a first input of the differential structure amplifier and to a second input of the differential structure amplifier through a pull-up resistor.
