Subthreshold circuits are an ideal choice for ultra low power, moderate throughput applications. In subthreshold region to meet the ultra-low power requirement of energy constrained devices, supply voltage less than the threshold voltage is applied. At same frequency, subthreshold circuits show orders of magnitude power saving over superthreshold circuits. In subthreshold operating region, minute...
This paper investigates a robust 1-bit static full adder using FinFET at near-threshold region (NTR), a design space where the supply voltage is approximately equal to the threshold voltage of the transistors. This region provides minimum-energy point for the different frequency of operation with more favorable performance and variability characteristics. The proposed design features higher computing...
Optimization of power and speed is a very important issue in low-voltage and low-power applications. In this paper, a 1-bit full adder cell has been successfully analyzed by assigning high-threshold voltage to some transistors and low-threshold voltage to others. Moreover, a robust full adder circuit using dual threshold voltage MOSFETs (DT-MOS) has been proposed. The proposed design features lower...
