ABSTRACT:
A switched-capacitor filter of the present invention constituted in the form of a semiconductor integrated circuit has an input circuit which consists of at least one noninversion-type switched-capacitor and at least two inversion-type switched-capacitors that are connected in parallel with each other. The two inversion-type switched-capacitors have different writing timings and reading timings relative to each other. With this setup, capacitances of the switched-capacitors need not be extremely increased even when it is desired to maintain a zero-point frequency of the filter at a very low value. Further, there is no need of providing a circuit such as sample holding circuit which requires extra area and consumes additional electric power.
