Abstract :
A technique for developing table-based macromodels which represent the input and output characteristics of digital integrated circuits is presented. A table-based macromodel is presented for the input characteristics of a FTTL NAND gate. A series resistor, a series inductor, a shunt nonlinear resistor and a shunt nonlinear capacitor model the input and output characteristics of the device. A current source can be added to the output characteristics to model the driver characteristics of the device. The model for the input characteristics is verified by comparing measured S-parameters of the actual device to simulated S-parameters of the proposed model
