ABSTRACT:
A multiple-phase switching circuit includes an alternative signal generator for generating a plurality of alternative signals according to a switching signal, and a multiplexer for receiving a plurality of clock signals and outputting a target clock signal according to the alternative signals. Only one of the alternative signals generated by the alternative signal generator is in a first logic level, while the other alternative signals are in a second logic level. The alternative signal generator changes the logic level of a first alternative signal having the first logic level into the second logic level, and changes the logic level of a second alternative signal adjacent to the first alternative signal into the first logic level.
