Patent ID: 8766834

Claim:
A discrete-time analog circuit comprising: a rotating capacitor circuit that includes at least one input line; at least one coefficient circuit that includes a potential holding section that amplifies input potential or input charge, an input line of the potential holding section being connected to the at least one input line of the rotating capacitor circuit and n charge holding sections disposed in series with the potential holding section and in parallel with each other, an output line of the potential holding section being connected to the n charge holding sections via switches; and a circuit connection switching section that sequentially changes the pairing of a first charge holding section and a second charge holding section among the n charge holding sections, the first charge holding section being connected to the potential holding section and charged thereby, the second charge holding section being connected to the input line not via the potential holding section and sharing charge with the rotating capacitor circuit or being held at the potential at the rotating capacitor circuit.
