Complementary Self-Biased Scheme for the Robust Design of CMOS/SET Hybrid Multi-Valued Logic
نویسندگان
چکیده
We propose a new technique to enhance the characteristics of CMOS/SET hybrid multi-valued logic (MVL) circuits in terms of their stability and performance. A complementary self-biasing method enables the SET/CMOS logic to operate perfectly well at high temperature in which the peak-to-valley current ratio of Coulomb oscillation severely decreases. The suggested scheme is evaluated by SPICE simulation with an analytical SET model, and it is confirmed that even SETs with a large Si island can be utilized efficiently in the multi-valued logic. We demonstrate a quantizer implemented by SETs with a 90-nm-long Si island on the basis of measured device characteristics and SPICE simulation, which shows high resolution and small linearity error characteristics.

A SPICE (simulation program with integrated circuit emphasis) model for a single-electron transistor (SET) was developed based on the physical phenomena in realistic Si SETs and was implemented into a conventional circuit simulator. In the proposed model, the SET current calculated using an analytic model is combined with the parasitic MOSFET (metal-oxide semiconductor field effect transistor) ...

In this paper, a novel multi-valued logic gate set is designed by using only current-mode CMOS circuits. The gate set consists of min, max, inverter, literal, and cyclic operators based on a current-mode, versatile, novel threshold topology. They are shown to exhibit better static and dynamic behavior and consume less area compared to previous MVL design topologies and binary-logic counterparts...
