Adiabatic dynamic logic

With adiabatic techniques for capacitor charging, theory suggests that it should be possible to build gates with arbitrarily small energy dissipation. In practice the complexity of adiabatic approaches has made them impractical. We describe a new CMOS logic family-Adiabatic Dynamic Logic (ADL)-that is the result of combining adiabatic theory with conventional CMOS dynamic logic. ADL gates are simple, general, readily cascadable, and may be fabricated in a standard CMOS process. Simulation and fabrication test results indicating that ADL offers an order of magnitude reduction in power consumption over conventional CMOS circuitry.<
