Abstract

Switching lattices consisting of four-terminal switches are introduced as area-efficient structures to realize logic functions. Many optimization algorithms have been proposed, including exact ones, realizing logic functions on lattices with the fewest number of four-terminal switches, as well as heuristic ones. Hence, the computing potential of switching lattices has been justified adequately in the literature. However, the same thing cannot be said for their physical implementation. There have been conceptual ideas for the technology development of switching lattices, but no concrete and directly applicable technology has been proposed yet. In this study, we show that switching lattices can be directly and efficiently implemented using a standard CMOS process. To realize a given logic function on a switching lattice, we propose static and dynamic logic solutions. The proposed circuits as well as the compared conventional ones are designed and simulated in the Cadence environment using TSMC 65nm CMOS process. Experimental post layout results on logic functions show that switching lattices occupy much smaller area than those of the conventional CMOS implementations, while they have competitive delay and power consumption values.
