Beschreibung
Zusammenfassung:	A signal processing circuit includes: a filter circuit that removes noise from a target signal; and a controller that controls the filter circuit. The filter circuit includes: a CMOS switch including a first MOSFET and a second MOSFET having different channel types and connected in parallel; and a capacitor electrically connected between an output of the CMOS switch and a ground potential. The controller switches a state of the CMOS switch between a first state in which the first MOSFET is in an ON state and a second state in which the first MOSFET is in an OFF state and the second MOSFET is in an ON state. An ON resistance value of the second MOSFET is higher than an ON resistance value of the first MOSFET.
