Abstract
A waveform shaping circuit is configured without including a diode that is affected by temperature. The waveform shaping circuit includes: a capacitor with one end into which a differential signal Vdis inputted and another end connected to an output; an impedance element that has one end connected to the other end of the capacitor and another end into which a target constant voltage is applied; a switch circuit that is constructed of a series circuit with an impedance element and a switch without including a diode, has one end connected to the output, and has another end into which the target constant voltage is applied; and a switch control circuit that shifts the switch into an on state during a low voltage period in an AC component of the differential signal and shifts the switch to an off state during a high voltage period of the AC component.
