An analytical method based on the classical perturbation method and the harmonic balance method is presented to analyze the distortion due to circuit nonlinearities. Starting from the time‐domain‐modified nodal analysis formulation for a nonlinear dynamic circuit, a calculation procedure of the periodic solution is developed, leading to general formulae for harmonics and nonlinear distortion figures. These formulae are then particularized for the widely used polynomial and exponential nonlinearities. Circuit simulations are performed showing the accuracy of the presented formulae.
