In this paper, we present a novel computing paradigm using a non-equilibrium electronic ratchet which is capable of driving current in the absence of an applied drain bias. By using a time varying, spatially asymmetric potential, we demonstrate that it is possible to create a net current from drift-diffusion processes of charge carriers. This is especially useful in reducing static dissipation encountered in conventional logic circuits. In addition, since the electronic ratchet acts as voltage-controlled current source, we find that the dynamic dissipation associated with charging/discharging of load capacitors is also decreased. Furthermore, we show that the ratchet device is naturally amenable to a dissipation reduction technique known as adiabatic clocking. Because of the unique charging mechanism of the ratchet, timing constraints on logic inputs—an important drawback of conventional adiabatic circuits—are not needed to achieve adiabatic computation.
