Abstract
An all-pass filter circuit includes a first terminal to which an input signal is input, a capacitor having a first electrode connected to the first terminal and a second electrode, a current amplifier circuit which is configured by MOS transistors, has an input terminal connected to the second electrode and supplied with a first signal output from the capacitor, and outputs a second signal based on conductance thereof, a second terminal to which a control signal for controlling the conductance is input, and an adder circuit which is configured by MOS transistors and adds the second signal and input signal together to output a third signal.
