Abstract
A timing signal generating circuit receives a plurality of input signals of differing phases and generates a timing signal having a phase intermediate therebetween. The timing signal generating circuit has a plurality of current polarity switching circuits, and a voltage level correction circuit. Each of the current polarity switching circuits is provided between a plurality of current sources and acts to switch an output current polarity in accordance with a corresponding one of the input signals. The voltage level correction circuit corrects the voltage level of a phase-combined signal produced by combining weighted outputs of the plurality of current polarity switching circuits.
