EFFICIENT SOLUTION METHOD FOR UNIFIED NONLINEAR MICROWAVE CIRCUIT ANDNUMERICAL SOLID-STATE DEVICE SIMULATION

A simple and very efficient harmonic-balance technique is presented th at is suitable for the steady-state analysis of nonlinear microwave an d millimeter-wave circuits that require physics-based, fully numerical simulations of charge carrier transport in the solid-state device. Th e practical integration of a numerical device simulator with a nonline ar circuit simulator requires a robust and fast circuit solution algor ithm. The new circuit solution algorithm was applied to a test simulat ion of a 100- to 300-GHz multiplier circuit, achieving a savings in co mputational effort of 98% and a reduction in execution time by a facto r of 33 over contending harmonic-balance techniques.
