摘要：
According to one embodiment, a circuit comprises a first resistor configured to have one end to which a first voltage is input and the other end which outputs a second voltage and a first amplifier configured to have an inverting input connected to the other end of the first resistor and a noninverting input to which a third voltage is input. The circuit further comprises a first capacitor configured to have one end to which an output of the first amplifier is input and the other end to which the other end of the first resistor is connected. An output of the first amplifier or an output of a second amplifier connected to the other end of the first resistor is a fourth voltage. In the circuit, the first resistor and a mirror capacitance composed of the first capacitor and the first amplifier constitute a low-pass filter.
