title = "An Automatic Offset Compensation Sense Amplifier Featuring High Readout Reliability for SRAM",
abstract = "With technology nodes aggressive scaling down, offset voltage has been emerging as one of the critical readout reliability issues of SRAM. This paper proposes a method named automatic compensation sense amplifier (ACSA), to tackle it by identifying the direction of offset and compensating automatically. This method obtains and stores the offset direction through one-time sensing, and then auxiliary transistors in corresponding branches are turned on for current compensation. The circuit implementation of the method is evaluated with SMIC 55-nm technology, operated at a supply voltage of 1.2 V. The proposed ACSA achieves a 66.19\% reduction in voltage offset compared to conventional Current Launch SA (CLSA), and a 30.6\% reduction compared to conventional Voltage Launch SA (VLSA).",
