Abstract

A sampling circuit and a receiver are provided having a high flexibility of filter design and excellent characteristics for removing an interfering wave. Provided also are a sampling circuit and a receiver having a low level of the higher harmonic spurious. The sampling circuit includes a charge sampling circuit, which executes sampling of an input signal, and a plurality of charge sharing circuits connected in parallel to the output stage of the charge sampling circuit. The charge sharing circuits include a charge sharing circuit group having transmission functions different from one another, a synthesis circuit, which is arranged at the output side of the charge sharing circuit group and synthesizes the outputs of the charge sharing circuits, and a digital control unit, which outputs a control signal for controlling the operation of the charge sharing circuit group and the synthesis circuit.
