Performance Projection of Negative Capacitance Complementary FET (NC-CFET): Device-Circuit Co-design

In this paper, we have compared the negative capacitance complementary FET (NC-CFET) from a device-circuit perspective with the experimentally demonstrated CFET. NC-CFET could potentially offer additional advantages over conventional CFET, like enhancement in the sub-threshold behavior, reduction in threshold voltage variability, improvement in noise margin, low supply voltage, and high-speed operation, etc. Detailed circuit-level simulations have been used to analyze the performance gains with NC-CFET.
