New computational technique for periodic distortion analysis of communication circuits

A new approach and technique for periodic distortion analysis is proposed. It is computationally efficient in comparison with complete nonlinear steady-state analysis. In contrast with the Volterra series approach this technique does not require high order derivatives of the device models. The numerical scheme of periodic distortion analysis is described. The technique is illustrated by examples of periodic distortion computation in nonlinear circuits using Spice-like simulator.
