Analytical transient response and propagation delay model for nanoscale CMOS inverter
ABSTRACT This paper presents a new analytical propagation delay model for nanoscale CMOS inverters. By using a non-saturation current model, the analytical input-output transfer responses and propagation delay model are derived. The model is used for calculating inverter delays for different input transition times, load capacitances and supply voltages. Delays predicted by the proposed model are in good agreement with those of transistor level simulation results from SPICE, with accuracy of 3% or better.
