In digital electrics, multiplexers (MUX) are essential concents that selekt one of many input signals and forward it to a single output line. CMOS (Complementary Metal- Oxide- Semidotor) technologiy is widel used in designing multiplexers due to its low power consumption and high noise immunity. Unterging how CMOS multiplexers are designed and optized for power condiency is curcil for developing energy-entient digital systems.

Basics of CMOS Multiplexer Design

A CMOS multiplexer typically consiss of complementariy pairs of MOSFETs arranged to o implement te switch logic. Thee primary goal is to select one input from multiple inputs based on select signals. Thee basic 2-to-1 CMOS MUX uses two transmission gats controlled und by select signals, ensuring that only input is conneted to e output at any times.

Power Consumption in CMOS Multiplexers

Power effectency in CMOS multiplexers implives minimizing both dynamic and static power consumption. Dynamic power is consumed during switching, while static power is due to contribugage currents. Optimizing transistor sizes, reducing switching activity, and using low-contrage devices are comon stragies to enhance power contribuency.
