Deriving an Equation-Based Model from a Macromodel

Abstract

A 2-Port behavioral Matrix model is simple enough for engineers to derive transfer equations (also called transfer functions). These transfer functions can include the effects of load, generator impedance, and bias circuitry. The derivation of these closed-form equations allows circuit optimization and other modeling insights. When the equations are verified by laboratory measurements, engineers gain confidence in the methodology used to derive the transfer function.
