High speed and low swing interface circuits using dynamic over-driving and adaptive sensing scheme

Abstract

In this paper, we propose novel interface circuits using Dynamic Over-Driving (DOD) and Adaptive Sensing (AS) scheme for high speed and energy-efficient interface on a chip. Our AS-receiver makes it possible to use very low swing because of its good noise immunity against the threshold voltage variations, and our DOD-driver reduces data transmission time even through heavy load capacitances. The simulation results show that the reduction of approximately 20% speed and 40% energy consumption is achieved for the proposed circuits, as compared with the conventional full CMOS inverters at low supply voltage (=1.5 V).
