Abstract :
With ever increasing power density and temperature variations within chips, it is very important to correctly model temperature effects on the devices in a compact way. In this paper, it is first shown that the temperature dependencies of the mobility and the saturation velocity need to be treated separately in modeling the current with temperature effects. Then, a new compact temperature-dependent model is presented for the on-current and transient behavior of a CMOS inverter based on the alpha-power law. The proposed model is shown to have an excellent agreement with BSIM3.
