Band pass filter and sensor device including the same

A sensor device comprising:

• first sensors;
• second sensors which form capacitances with the first sensors;
• a sensor transmitter connected to the first sensors, wherein the sensor transmitter supplies driving signals to the first sensors;
• and
• a sensor receiver connected to the second sensors, wherein the sensor receiver receives sensing signals from the second sensors, and the sensor receiver includes a band pass filter which filters the sensing signals,
• wherein the band pass filter includes:
• a first integrator including a first amplifier;
• a first high pass filter converter connected to a first input terminal, a second input terminal and a first output terminal of the first amplifier, wherein the first high pass filter converter time-divisionally provides N high pass filter conversion paths, wherein N is an integer greater than 1;
• and
• a first gain auxiliary component simultaneously connected to the first input terminal and the first output terminal of the first amplifier while the first integrator performs an integral function and simultaneously disconnected from the first input terminal and the first output terminal of the first amplifier while the integral function is not performed.
