Fluctuation suppression circuit

A fluctuation suppression circuit comprising:

• an electric charge supply circuit,
• wherein the fluctuation suppression circuit is configured to suppress fluctuation of a reference voltage supplied to a switched capacitor circuit having a differential configuration,
• wherein the switched capacitor circuit includes an input capacitor for charging an input voltage and a reference capacitor for charging the reference voltage, and the input capacitor and the reference capacitor are separately disposed, and
• wherein the electric charge supply circuit is configured to:
• generate an offset electric charge by adopting a predetermined offset voltage, for offsetting a charged or discharged electric charge generated in the switched capacitor circuit;
• and
• supply the offset electric charge to two reference input nodes, which are supplied with the reference voltage, in the switched capacitor circuit.
