    Abstract: A band pass filter circuit includes an amplifier circuit having a first input terminal to receive a first analog signal; a second input terminal to receive a second analog signal; first and second output terminals; capacitors; and switches. In a first switching mode, the switches are controlled so that the amplifier circuit and a first group of the capacitors connected between the input and output terminals operate as a first band pass filter filtering the first and second analog signals in a differential mode. In a second switching mode, the switches are controlled so that the amplifier circuit and second and third groups of the capacitors form second band pass filters filtering each of the first and second analog signals in a single-ended mode.
