Patent ID: 8682625

Claim:
A method, implemented by a computer, for analyzing electrical properties of a circuit, the method comprising: providing a network model of the circuit having at least one port, wherein the network model includes at least one network parameter, the network parameter being associated with the port and being defined over a frequency range; converting, by the computer, the network parameter into an intermediate network parameter; the intermediate network parameter having first and second portions; providing a value indicative of an electrical property of the port in a direct current (DC) condition; identifying first and second frequencies in the frequency range, the first frequency being lower than the second frequency, wherein the first and second frequencies define a frequency sub-range; replacing the first portion of the intermediate network parameter with the value when a frequency associated with the intermediate network parameter is lower than the first frequency; replacing the first portion of the intermediate network parameter with a transitional value when the frequency associated with the intermediate network parameter is within the frequency sub-range; and converting, by the computer, the intermediate network parameter with the replaced first portion into an updated network parameter.
