摘要： Disclosed herein is an integrator including: a resistive element connected to an input terminal; an operational amplifier configured to receive, through the resistive element, an input signal that has been supplied to the input terminal; and a voltage regulator circuit connected to an intermediate node between the resistive element and the operational amplifier. The voltage regulator circuit has a first current source connected to the intermediate node, and a switch connected between the intermediate node and the first current source and selectively turning ON or OFF.
