Abstract :
The analysis of complex front-ends containing many nonlinear devices and supporting signal waveforms with many spectral components can be efficiently handled by the harmonic-balance technique coupled with Krylov-subspace methods. The paper extends this approach to the computation of the front-end noise figure in the presence of a strong interfering signal.
