It is a modified and more efficient form of Newton-Raphson iteration based harmonic balance (HB) technique. It solves the convergence problems of the HB technique at high drive levels. The proposed method makes use of the parametric dependence of the circuit responses on the excitation level. It first computes the derivatives of the complex amplitudes of the harmonics with respect to the excitation level efficiently and then finds the Pade approximants for the amplitudes of the harmonics using these derivatives.EnglishSteady-stateNonlinear circuitsFrequency domain analysisMicrowave theory and techniquesMicrowave circuitsTime domain analysisConvergenceMicrowave devicesLinear circuitsEarArticle10.1109/81.5458371558-1268
