Abstract
A model is proposed for computing the propagation delay of a CMOS inverter. The model takes into account the shape of the input waveform, the capacitive load, and the transconductances of the PMOS and NMOS transistors. The model uses either an analytical solution or a power series approximate solution for the differential equations that govern the behavior of the inverter. Regression equations are developed for the times spent in different regions of operation. The equations help in improving the speed of the program
