An 8/spl times/8-b nRERL serial multiplier for ultra-low-power applications

An 8/spl times/8-b nRERL serial multiplier is implemented in a 0.6-/spl mu/m n-well 3-metal CMOS process. nRERL (nMOS Reversible Energy Recovery Logic) is a new reversible adiabatic logic circuit, which can be operated at the leakage-current level for ultra-low-energy applications. Measurement results showed that the nRERL serial multiplier consumed only 0.9% of the energy dissipation by the static CMOS type at the operating frequency 100 kHz at 5 V, where its adiabatic and leakage losses were about equal.
