    Dear reader,

    I have been designing neural front end architecture for collecting multiple channel neural data. Each channel/electrode is connected to a preamplifier stage for signal amplification. The outputs from the preampifiers are to be multiplexed. I am stuck with the design of analog multiplexer. Does an 8 to 1 multiplxer involves 8 transmission gates switches with outputs connected together? Any explanations or links?

    Yes, an 8:1 mux does have 8 transmission gates with one side connected together. The transmission gates are bidirectional and either side can be used as an input or output (multiplexer or de-multiplexer).
