Reduce energy consumption - causes of CMOS inverter switching delay and its influencing factors

Abstract

This paper offers a comprehensive examination of the Complementary Metal-Oxide-Semiconductor (CMOS) inverter, a quintessential component in contemporary digital integrated circuits, renowned for its minimal power consumption, robust noise resistance, and adaptability. The focus of this investigation is the switching delay of the CMOS inverter, a pivotal attribute that exerts substantial influence on the overall functionality of the circuitry. This discourse undertakes a detailed exploration of the factors contributing to the CMOS inverter switching delay, dissecting the influence of both intrinsic and extrinsic elements. Initially, the analysis delineates the origins of the switching delay in CMOS inverters, categorizing them into internal and external determinants. Subsequently, the study meticulously examines methodologies to modulate these factors, thereby achieving effective control over the delay. By implementing strategic optimizations, this research aims to diminish latency and enhance operational efficiency. Through a theoretical lens, this paper elucidates the complex interplay between these inherent and external factors, culminating in the optimization of the CMOS inverter switching delay. The insights garnered from this analysis are poised to offer a substantive theoretical foundation for the design of more efficient and reliable digital circuits in the current technological milieu.
