A Current-Mirror Winner-Take-All Sense Amplifier for Low Voltage SRAMs

Song Jia, Heqing Xu, Fengfeng WU, Yuan Wang

Abstract

We propose a current mode sense amplifier that uses a current-mirror to increase the bitline sensing current, which dominates the sensing speed. A comparison of the sensing delay shows that the proposed sense amplifier can provide about 12.6∼15.4% improvement depending on different bitline loads in sensing speed over original WTA scheme.
