Analysis and Comparison of Various Sense Amplifier Topologies for SRAM

Abstract: Sense Amplifier are one of the most crucial circuits in the field of CMOS memories. Memory access time and overall memory power dissipation both are resultant by their performances. The existing Current Mode Sense Amplifier has ability to quickly to amplify a small differential signal Bit Lines (BLs) and Data Lines (DLs) to the full CMOS logic level without requiring a large input voltage swing. Here Analysis and Comparison done using 45nm CMOS technology shows Sensing Speed, Reliability, Power Consumption can be improved to a considerable extent. Power dissipation is improved.
