| Abstract: | We propose here an efficient algorithm for finding the steady-state response of stiff non-linear circuits. It is based on a frequency-domain relaxation method and can be applied efficiently to obtain the steady-state waveforms of both periodic systems and multi-frequency-component systems. the solution at each iteration is obtained by solving an associated linear time-invariant circuit at every frequency component via modified nodal analysis. Our algorithm is very simple and can be applied efficiently to solve a large class of practical non-linear communication circuits which are notoriously stiff and hence rather time-consuming to solve with existing methods. |
