Due to quadratic dependence of switching power on supply power, supply scaling leads to significant power savings. However, as the supply voltage is lowered, drive current of a MOSFET becomes more sensitive to PVT variations, resulting in many challenges in the design of digital circuits. This research mainly focuses on PVT tolerant design of digital circuits such as memory and logic in ultra-low voltage operation. In memory, low supply voltage results in read stability problems. Recently, an 8T bit-cell was developed to improve the read stability. However, its application is limited due to large area penalty (above 30%). We propose a hybrid SRAM architecture for video memory, where only critical MSB bits are stored in the 8T bit-cells. Thi...
