4:1 mux using pass transistor logic

Advantages of using transmission gate logic.

  • A CMOS transmission gate can be constructed by parallel combination of nMOS and pMOS transistors, with complementary gate signals.
  • The main advantage of CMOS transmission gate compared to nMOS transmission gate is to allow the input signal to be transmitted to the output without the threshold voltage attenuation.
  • It allows full rail transition i.e. ratioless logic
  • The equivalent resistance is relatively constant during transition.
  • Some gates are efficient implemented using transmission gate.
