Abstract:
1. A method for generating a global equivalent circuit model to represent a family of electrical circuit components to be mounted upon a given substrate, the global equivalent circuit model incorporating substrate-dependent parameters, the method comprising the following steps: selecting a plurality of electrical circuit components from a family of electrical circuit components for which a global equivalent circuit model is desired, the family of electrical circuit components comprising a plurality of electrical circuit components having values within a predetermined range of values and wherein the plurality of electrical circuit components selected does not include all of the electrical circuit components in the family; measuring electrical response of each of the plurality of selected electrical circuit components; extracting variable values and circuit element values from a measured electrical response for each of the plurality of selected electrical circuit components; selecting an unmeasured electrical circuit component from the family of selected electrical circuit components, wherein the unmeasured electrical circuit component is not one of the plurality of selected electrical circuit components for which an electrical response has been measured; identifying the variable values for the measured electrical circuit component of the plurality of selected electrical circuit components that has a value above the value of the unmeasured electrical circuit component and determining the corresponding circuit element values for the measured electrical circuit component of the plurality of electrical components that has a value above the value of the unmeasured electrical circuit component; identifying the variable values for the measured electrical circuit component of the plurality of selected electrical circuit components that has a value below the value of the unmeasured electrical circuit component and determining the corresponding circuit element values for the measured electrical circuit component of the plurality of selected electrical circuit components that has a value below the value of the unmeasured electrical circuit component; and performing linear interpolation between the identified circuit element values for the measured electrical circuit component of the plurality of selected electrical circuit components that has a value above the value of the unmeasured electrical circuit component and the identified circuit element values for the measured electrical circuit component of the plurality of selected electrical circuit components that has a value below the value of the unmeasured electrical circuit component resulting in an approximation of the electrical circuit component value for the unmeasured electrical circuit component from the family of selected electric circuit components.
