An 8 x 8 nRERL serial multiplier for ultra-low-power applications

Abstract

An 8 x 8-b nRERL serial multiplier is implemented in a 0.6- m n-well 3-metal CMOS pro- cess. nRERL (nMOS Reversible Energy Recov ery Logic) is a new reversible adiabatic logic circuit, which can be operated at the leakage-current lev el for ultra- low-energy applications. Measurement results show ed that the nRERL serial multiplier consumed only 0.9 % of the energy dissipation of the static CMOS one at the operating frequency 100 kHz at 5V, where its adiabatic and leakage losses were about equal.
