1. A sensor device comprising:
a plurality of first sensors;
a plurality of second sensors generating a mutual capacitance with the plurality of first sensors;
a sensor transmitter connected to the plurality of first sensors, the sensor transmitter supplying driving signals to the plurality of first sensors; and
a sensor receiver connected to the plurality of second sensors, the sensor receiver receiving sensing signals from the second sensors,
wherein the sensor receiver includes a band pass filter including a plurality of paths connected in parallel, and wherein a first path among the plurality of paths sequentially includes a first input mixer, a first filter, and a first output mixer,
wherein a frequency and a phase of a first input clock signal received by the first input mixer are equal to a frequency and a phase of a first output clock signal received by the first output mixer.
