ABSTRACT:
A serial differential cell includes complementary positive and negative pass gate networks coupled to a differential amplifier, which produces a valid logic output. The complementary pass gate networks can include one or more pass gate stages coupled in series. In a serial differential multiplexer, a stage includes first and second inputs, and a select input for controlling which input is passed to an output of the stage. For multiple stages, the output of a first stage is coupled to one of the inputs of a next stage. A number of stages can be coupled together in series to form networks, with a differential amplifier coupled between positive and negative networks where necessary to provide a valid logic output.
