Adiabatic operation promises large reductions of power consumption because it does not dissipate energy. This paper reviews recent progress in adiabatic circuits. First, a charge recycle regenerator with the tank capacitor is discussed. Next, an adiabatic charging binary decision diagram circuit is discussed. In the circuit, a gate-level pipeline can be realized by using four charge-recycling clocks. Also reviewed is an adiabatic circuit based on clocked energy reversible logic, which can maintain the complementary-metal-oxide-semiconductor circuit architecture. Finally, adiabatic staticrandom- access-memory is covered, which is structurally close to the conventional SRAM. These adiabatic circuits are very effective in the nanoscale region because they can avoid hot carrier effects and electromigration owing to their gradual charging characteristics. This review also covers some important recent patents.
