Abstract:
In some aspects, a method for phase multiplexing includes receiving a plurality of phases, selecting one of the plurality of phases based on a select signal using a multiplexer, and outputting the selected one of the plurality of phases at an output of the multiplexer. The method also includes gating the output of the multiplexer during a glitch at the output of the multiplexer.
