DESIGN OF TWO-PHASE SINUSOIDAL POWER CLOCK AND CLOCKED TRANSMISSION GATE ADIABATIC LOGIC CIRCUIT

First the research is conducted on the design of the two-phase sinusoidal power clock gen- erator in this paper. Then the design of the new adiabatic logic circuit adopting the two-phase sinusoidal power clocks—Clocked Transmission Gate Adiabatic Logic (CTGAL) circuit is presented. This circuit makes use of the clocked transmission gates to sample the input signals, then the output loads are charged and discharged in a fully adiabatic manner by using bootstrapped N-Channel Metal Oxide Semiconductor (NMOS) and Complementary Metal Oxide Semiconductor (CMOS) latch structure. Finally, with the parameters of Taiwan Semiconductor Manufacturing Company (TSMC) 0.25μm CMOS device, the transient energy consumption of CTGAL, Bootstrap Charge-Recovery Logic (BCRL) and Pass-transistor Adiabatic Logic (PAL) including their clock generators is simulated. The simula-tion result indicates that CTGAL circuit has the characteristic of remarkably low energy consumption.

Design of adiabatic two's complement multiplier-accumulator based on CTGAL

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.
