A Reliable, Process-Sensitive-Tolerant Hybrid Sense Amplifier for Ultralow Power SRAM
A novel ultra-high speed, compact and least sensitive to process variation, hybrid sense amplifier is designed for ultra-low power SRAM. Precisely sized Current Mode Circuit (CMC) is designed to provide differential current from bit-lines. The authors eliminate the global sensing stage to save silicon area and sized the output buffers to achieve full logic swing at the output of proposed sense amplifier. The proposed design improves the sensing delay and shows excellent tolerance to process variations as compared to best published latch type sense amplifier.
