Fast Frequency Sweep Analysis of Passive Miniature RF Circuits Based on Analytic Extension of Eigenvalues

A fast frequency sweep approach based on analytic extension of eigenvalues (AEE) is presented and investigated for an efficient analysis miniature passive RF circuits. In this approach, eigenvalue decomposition performed to the Z-parameters circuit components at one or a few frequencies, applied obtain all other frequencies within band interest. For electrically small components, frequency-independent characteristic inductances capacitances, as well frequency-dependent resistances, are extracted from sampling frequencies. The parameters then used approximate Z- Y-parameters predict responses over entire band. accuracy evaluated by comparing it with results full-wave analysis. It found that proposed AEE very accurate relative error less than 1% circuits whose electrical sizes smaller tenth wavelength more general powerful lumped equivalent
