Acceleration techniques for the circuit simulation in the frequency domain

Describes the exploitation of latency in frequency domain circuit analysis. First, the authors define frequency domain latency as the property of a circuit in harmonic analysis, and discuss several simulation algorithms based on the direct method and the relaxation method. They then propose a multirate sampling technique for the FFT (fast Fourier transform) in the harmonic balance method. Finally, they apply the present techniques to simple analog circuit simulation and verify its availability
