Abstract
A mixer which has an enhanced frequency selection characteristic and generates no pass loss is realized without using an operation control signal having a frequency higher than a sampling frequency. Provided are a time control sectionfor supplying control signals, a first switched capacitor circuitfor outputting a discrete time sample stream of the input signalin accordance with integration operation control signals Loand Lo, and a second switched capacitor circuitfunctioning as a high-order IIR filter by sharing a charge, and a frequency of each of the integration operation control signals Loand Lois higher than frequencies of other control signals.
