Sensor device and driving method thereof

A sensor device of the present invention includes first sensors receiving a plurality of driving signals; second sensors outputting a plurality of sensing signals in response to the driving signals; and a sensor receiver connected receiving the sensing signals from the second sensors, and including a band pass filter filtering the sensing signals. The band pass filter includes a multi-path filter in which a frequency of the driving signals is set as a center frequency; a gain amplifier amplifying signals filtered through the multi-path filter according to a predetermined gain value; and a buffer isolating the multi-path filter and the gain amplifier from each other.
