摘要

感应放大器（SA）的性能对高速 SRAM 至关重要。在低电压下，大偏移和慢分辨感应放大器会成为 SRAM 性能的瓶颈，因此，人们非常重视设计速度更快的感应放大器，但往往以牺牲面积为代价。在本简介中，我们提出了一种容差电源升压电压检测放大器（SBVSA），在 22nm CMOS 技术中，它比传统电压检测放大器（CVSA）在 5 美元/sigma $ 时的速度快 45%。实现这一增益时，SRAM 实例的面积开销不到 1%，而在 22nm CMOS 技术中，实例的读取性能最多可提高 9%。

Up to 45% Faster Supply Boosted Voltage Sense Amplifier (SBVSA) for High-Speed SRAMs

The performance of Sense Amplifiers (SAs) is critical to high-speed SRAMs. Large-offset and slow-resolving SAs can create a bottleneck in the SRAM performance at low voltages because of which a lot of emphasis is laid on designing faster SAs, often at the cost of area. In this brief, we propose a variation-tolerant Supply Boosted Voltage Sense Amplifier (SBVSA) that is up to 45% faster at

$5\sigma $

than a Conventional Voltage Sense Amplifier (CVSA) in 22nm CMOS technology. This gain is achieved with an area overhead of less than 1% in SRAM instances while improving the read performance of the instances by up to 9% in 22nm CMOS.
