Adiabatic logic is an implementation of reversible logic in CMOS where the current flow through the circuit is controlled such that the energy dissipation due to switching and capacitor dissipation is minimized. Dual-rail adiabatic logic implemented with reversible principles has also been demonstrated to significantly reduce differential power consumption. The dual-rail adiabatic logic show reduction in average and differential power, making this design methodology advantageous in applications where security is the primary design metric and operating frequency is slower, such as smart cards.
