Adiabatic circuit

Adiabatic circuits are low power circuits which use "reversible logic" to conserve energy. [1] Unlike traditional CMOS circuits, which dissipate energy during switching, adiabatic circuits attempt to conserve charge by following two key rules:

Never turn on a transistor when there is a voltage potential between the source and drain.
Never turn off a transistor when current is flowing through it.

While this is an area of active research, current techniques rely heavily on transmission gates and trapezoidal clocks to achieve these goals.
