Abstract
We propose a new design scheme for a Booth encoder based on clocked transmission gate adiabatic logic (CTGAL). In the new design the structural complexity of the Booth encoder is reduced while the speed of the multiplier is improved. The adiabatic two’s complement multiplier-accumulator (MAC) is furthermore a design based on the CTGAL. The computer simulation results indicate that the designed circuit has the correct logic function and remarkably less energy consumption compared to that of the MAC based on complementary metal oxide semiconductor (CMOS) logic.
