DESIGN AND PERFORMANCE ANALYSIS OF HIGH-PERFORMANCE LOW POWER VOLTAGE MODE SENSE AMPLIFIER FOR STATIC RAM

In the prominent era of the digital world and Very Large-Scale Integration (VLSI) circuits, Static Random Access Memory (SRAM) provides a vital con-tribution to low-power and high-speed performance. Sense Amplifiers (SA) are a part of Complementary Metal-Oxide-Semiconductor (CMOS) memories used to read the stored information. This paper indicates a Dual-Voltage, Dual-Tail Level Restoration Voltage Latch Sense Amplifier (DVDTLR-VLSA). The design has been implemented using the LT SPICE tool at 180 nm technology node with a 1.8 V supply. Per-formance comparison of existing SA presented in lit-erature with the proposed SA is examined based on different parameters like power, energy, delay, and current. The proposed design maintains power at 2.167 mu W that is decreased to half as against Dual Switch Transmission Gate Voltage SA (DTGVSA) and shows an appreciable depletion. Also, the current and delay results are improved. Dimensional analysis is also done for the proposed SA to examine the perfor-mance. After that, the effect of sleep transistors on the proposed SA examines the performance in comparison to delay and power parameters without sleep transis-tors. The DVDTLR-VLSA has minimal energy and power. Also, the delay is improved which may be de-termined more advisable for low-power operations.
