Power and Area Efficient Sense Amplifier Based Flip Flop with Wide Voltage and Temperature Upholding for Portable IoT Applications

Prashant Teotia, Owais Ahmad Shah

Abstract


A Sense Amplifier based flip-flop (SAFF) capable of operating unfailingly at wide voltage and temperature ranges is proposed in this work. The proposed flip-flop (FF) has a single ended latch design which results in significant improvement in power and area requirements. The modified sense amplifier along with single ended latch design enables robust and low power operation at all variations in the input data activity. The proposed SAFF is developed in 32nm CMOS technology, and a thorough and conclusive investigation with corner case simulation for wide Process, Voltage and Temperature (PVT) variations is carried out in order to verify the design utilization. Comprehensive comparison and analysis with previously available state-of-art SAFFs validates that the proposed SAFF is functional at wide voltage ranges for temperature changes of 120 ℃ to -40 ℃ while upholding better and optimal power and power delay product (PDP) results. The proposed FF because of power efficiency is best suited for portable Internet of Things (IoT) devices.
