A variable threshold voltage keeper circuit technique is proposed for simultaneous power reduction and speed enhancement of domino logic circuits. The threshold voltage of a keeper transistor is dynamically modified during circuit operation to reduce contention current without sacrificing noise immunity. The variable threshold voltage keeper circuit technique enhances circuit evaluation speed b...

To model printing noise a binary noisy channel and a set of controlled gates are introduced. The channel input is an image created by a halftoning algorithm and its output is the printed picture. Using this channel robustness to noise between halftoning algorithms can be studied. We introduced relative entropy to describe immunity of the algorithm to noise and tested several halftoning algorithms.

Dynamic logic circuits are used for high performance and high speed applications. Wide OR gates are used in Dynamic RAMs, Static RAMs, high speed processors and other high speed circuits. In spite of their high performance, dynamic logic circuit has high noise and extensive leakage which has caused problems for the circuits. To overcome these problems Domino logic circuits are used which reduce...

Abstract —Neuron circuits have parallel operation features. VLSI implemented Neuron networks are suitable for high speed and low power consumption applications. Digital implementations have good noise immunity while analog neuron circuits have smaller size. This paper presents a mixed-signal neuron design. It uses digital input, output, and weight signals while keeps analog internal operation. ...
