Exploiting the asymmetric nature of interactions among hysteresis, “nonFET”, and DC characteristics, an a priori hysteresis modeling methodology has been proposed as an essential part of an improved model extraction flow for advanced PD SOI technologies. It has been successfully implemented on a state-of-the-art 90 nm technology demonstrating projected benefits, including minimum deviation of nonFET characteristics from hardware data, improved model extraction efficiency, improved model accuracy for hysteresis over a wide range of Vdd/T, and efficient implementation of automatic hysteresis optimization.
