METHOD OF GENERATING TRANSISTOR AC SCATTERING PARAMETERS SIMULTANEOUSLY WITH DC CHARACTERISTICS USING A SINGLE CIRCUIT SIMULATION WITH A SELF-CORRECTION SCHEME FOR THE ARTIFICIAL DC VOLTAGE DROPPED ACROSS THE 50-OHM RESISTOR REPRESENTING TRANSMISSION LINE IMPEDANCE

摘要

A method of generating transistor scattering parameters employs a single circuit simulation with a self-correction scheme for the artificial DC voltage dropped across the 50-Ohm resistor representing transmission line impedance. A sub-circuit without 50-Ohm transmission line resistance is used to compute transistor bias current via a current-controlled voltage source to compensate for the DC voltage dropped across a 50-Ohm resistor contained in the network.
