What is Transmission gate?

An analog switch made of an nMOS and a pMOS connected in parallel. The nMOS passes 0 well and the pMOS passes 1 well, so both values pass without voltage loss.

Field: MOSFET

Questions that mention Transmission gate (2)

  1. What is the advantage of a transmission gate, which connects an nMOS and a pMOS in parallel?
  2. In a pass transistor (switch) made of a single nMOSFET with its gate at the supply voltage VDD, how high does the output rise when passing an input of VDD?
