Abstract
This paper presents results of work to explore the feasibility of using resonant tunnelling diodes (RTDs) and conventional MOSFETs for the development of digital logic circuits. Based on the use of RTDs and MOSFETs, two different logic design styles fixed pull-down and fixed pull-up are proposed and evaluated. Fixed pull-up gates perform better than their CMOS counterparts with similar device sizes. Since the proposed fixed pull-down style avoids the use of series MOSFETs, for large fan-in gates it yields significantly better performance than the corresponding CMOS gates.
