On the propagation delay of CMOS inverters

Abstract

This research study delves into the propagation delay analysis in Complementary Metal-Oxide-Semiconductor (CMOS) inverters, aiming to uncover the factors contributing to it and exploring strategies to mitigate its impact. CMOS inverters, as pivotal constituents within digital integrated circuits, play a foundational role, making a thorough understanding of their propagation delay characteristics indispensable for the design of high-performance circuit. The research encompasses a comprehensive examination of propagation delay in CMOS inverters, addressing three key factors affecting it: load capacitance, transconductance parameters, and power supply voltage. Additionally, the study explores techniques for reducing propagation delay, including leveraging alternative materials and adopting specific layout designs. This study can provide insights into the sources of propagation delay in CMOS inverters and provide a comprehensive grasp of methods to alleviate it. By efficiently managing propagation delay, it becomes possible to enhance the overall performance and efficiency of CMOS circuits, thereby facilitating the development of advanced, high-speed digital systems.
