Design issues of arithmetic structures in adiabatic logic

[摘要] Since adiabatic logic uses a supply that incorporates both supply voltage andclock signal in one line, adiabatic logic systems have a built-inmicro-pipelined architecture. Considering this fact, different designconstraints have to be observed compared to static CMOS designs. Complexarithmetic building blocks, like multipliers, mainly consist of adders.Therefore, a comparison of adder structures is performed. Based on theseresults, multipliers and complex systems can be built. A Discrete CosineTransformation (DCT) is taken as example for an arithmetic system. Comparingan adiabatic logic implementation of a DCT to its static CMOS counterpart, asignificant saving factor of more than 10 can be achieved with the adiabaticsystem.
