Abstract :
This paper presents a simulation method to compute noise in autonomous and forced circuits using the harmonic balance (HB) formulation. Thanks to iterative linear solvers and multi-dimension conversion matrices, it can handle large multi-tone circuits to calculate phase noise spectra near and far from the carrier frequency. Its efficiency is illustrated with two real circuits.
