Assessment of SET Logic Robustness Through Noise Margin Modeling

Chaitanya Sathe, Surya Shankar Dan, and Santanu Mahapatra, Member, IEEE

Abstract—
A compact model for noise margin (NM) of single electron transistor (SET) logic is developed, which is a function of device capacitances and background charge (ζ). Noise margin is, then, used as a metric to evaluate the robustness of SET logic against background charge, temperature, and variation of SET gate and tunnel junction capacitances (CG and CT ....etc

BUILT IN SELF TEST FOR A CMOS ALU

Abstract:- A technique is proposed for implementing BIST (built-in self-test) in a CMOS arithmetic and logic unit (ALU). The approach covers single stuck-open faults and all functional faults that do not induce memory effects. The specific fault set covered by the test includes: (1) all single stuck-open faults on n and p transistors anywhere in the ALU (F1 faults); and (2) all functional faults that affect any single-bit slice of the (F2 faults), a functional fault being any fault that changes one combinati ....etc

Abstract
This paper proposes a two-phase scheme for removing salt-and-pepper impulse noise. In the first
phase, an adaptive median filter is used to identify pixels which are likely to be contaminated by noise
(noise candidates). In the second phase, the image is restored using a specialized regularization method
that applies only to those selected noise candidates. In terms of edge preservation and noise suppression,
our restored images show a significant improvement compared to those restored by using just nonlinear
filters or r ....etc

1. INTRODUCTION

GLOBAL Positioning System (GPS) receivers for the consumer market require solutions that are compact, cheap, and low power. Manufacturers of cellular telephones, portable computers, watches, and other mobile devices are looking for ways to embed GPS into their products. Thus, there is a strong motivation to provide highly integrated solutions at the lowest possible power consumption. GPS radios consist of a front-end and a digital baseband section incorporating a digital processor. While for the baseband processor, cost-reduc ....etc
