Abstract :
There are many communication circuits driven by multi-tone signals such as modulators and mixers. If the output frequency components are largely different to each other, the brute force numerical method will take an enormous computation time to calculate the steady-state responses, because the total period becomes very long. In this paper, we show a SPICE oriented algorithm based on the frequency domain relaxation method which can be efficiently applied to relatively large scale ICs
