Design and Analysis Latch Sense Amplifier Used in SRAM IC by Using Low Power Techniques

Abstract

In today's technologically advanced society, semiconductor chips are integral to most of our gadgets, necessitating small footprints and low power consumption for data storage and memory. SRAM plays a crucial role in meeting these requirements. This study employs Cadence Virtuoso software to design a high-performance sense amplifier circuit tailored for low-power SRAM applications. Various power reduction strategies were explored, leading to the implementation of an optimal solution in a modified SRAM design. The study examines the impact of power consumption and response time of the proposed sense amplifier by adjusting the width-to-length (W/L) ratio of transistors, power supply, and nanoscale technology. Detailed metrics on power usage and transistor count for different approaches are provided to identify the ideal technique. Our proposed low-power sense amplifier design demonstrates promising results, utilizing three variations of VLSI power reduction techniques to enhance efficiency. Low-power SRAMs are poised to advance memory-centric neuromorphic computing applications.
