Bandwidth extension for true single-phase clocked multiplexer

摘要

A true single-phase clocked multiplexer for outputting one of a plurality of input signals in synchronization with a clock signal and as selected by at least one select signal is provided. The multiplexer includes first transistors, second transistors, a first node between the first transistors, a second node between the second transistors, a third node coupled to the first node by one of the first transistors and to the second node by one of the second transistors, and a pre-charge transistor to couple the third node to a first voltage level. The first transistors are coupled to the first voltage level and configured to turn on in response to a gate voltage of a second voltage level different from the first voltage level. The second transistors are coupled to the second voltage level and configured to turn on in response to a gate voltage of the first voltage level.
