Abstract : The dynamic dissipation of CMOS circuits is becoming a major concern for designers of personal information systems and large computers. Here, we present new CMOS logic families, including Split-Level Charge Recovery Logic (SCRL), within which the transfer of charge between the nodes occurs quasistatically, thus having a power consumption that drops quadratically with operating frequency as opposed to the linear drop of conventional CMOS. The technique in these new families rely on explicitly reversible pipelined logic gates to provide the necessary information needed to recover most of the energy used in the computation. We report results of testing the first fully quasistatic 8x8 multiplier chip (SCRL-l).
