Abstract :
A model for evaluating the propagation delay, rise and fall time of NAND gates is proposed. The model includes the shape of the input waveform, the capacitive load, and the transconductances of the NMOS and the PMOS transistors. The effect of the position of the first active input is included in the model. The proposed model is compared with SPICE for accuracy and computation speed
