Resumen

In the past, Pass Transistor Logic (PTL) was widely used due to benefits in terms of speed and power consumption coming from the reduced number of transistors. However, issues such as threshold drop across the single-channel pass transistors and high sensitivity to process variations have prevented the use of PTL in advanced nanometer technologies. In this paper, we propose a novel logic family named Dual Mode Pass Logic (DMPL), which allows for high speed and low power consumption while maintaining robustness down to the sub-threshold voltage region. The DMPL effectively combines PTL to reduce energy and power consumption along with the flexibility of Dual Mode Logic (DML) to switch to a speed improved operating mode according to the system requirement. Simulation analysis performed on basic NOR/NAND gates implemented in 16 nm Finfet technology demonstrates that DMPL can reduce energy and power by 33% and 42% as compared to logically equivalent static CMOS design. Moreover, running frequency of a DMPL circuit can exceed that of its static CMOS counterpart by 84% when speed is mandatory. Additionally, DMPL gates demonstrate similar robustness as static CMOS implementations under process and temperature variations at lower supply voltages.
