Abstract
Provided is a microphone system insensitive to external noise, and the microphone system includes a microphone sensor that generates sensing data by sensing a change in sound pressure through a sensor bias voltage, a lead-out circuit that provides the sensor bias voltage for operating the microphone sensor, removes noise of the sensing data, and outputs the sensing data, a first pad that connects the microphone sensor and the lead-out circuit to each other and allows the sensor bias voltage to pass therethrough, and a second pad that connects the microphone sensor and the lead-out circuit to each other and allows the sensing data to pass therethrough.
