A Method for the Development of Indicators of a Transient Period Based on Short-Pulse Shapers in Asynchronous Adders

Abstract

The interest prevalent in the self-timed (ST) circuitry is related to the use of super-large integrated circuits. Circuits that enable increasing the degree of integration and power efficiency in combination with comparable performance are topical. A circuit of an asynchronous adder with a spacer two-rail code and an indicator of the transient process period based on CMOS transistors is proposed. A method of the circuitry configuration of the transient period indicator based on forming short pulses that correspond to the presence of a transient process is presented. A comparative analysis of the indicator’s performance demonstrates that the proposed method ensures a significant reduction in the number of components and power consumption. The efficiency of the proposed circuits is validated by simulation using the OrCAD PSpice circuit simulation software tool.
