| Abstract(in English) | There are many communication circuits driven by multi-tone signals such as modulators and mixers. In this case, if frequency components of the modulators are largely different, the brute force numerical method will take an enormous computation time to get the steady-state responses, because the step size must be chosen depending on the highest frequency input. In this paper, an efficient algorithm is shown to solve a communication circuit driven by multi-tone signals which is based on the frequency-domain relaxation method and the multi-dimensional Fourier transformation. The attenuation of the transient phenomena will mainly depends on the reactive elements such as capacitors and inductors, so we partition the circuit into two groups of the nonlinear resistive subnetworks and the reactive elements using the substitution sources. The steady-state response can be calculated in such a manner that the responses at each partitioning point have the same waveform. We have developed a simple simulator carrying out our algorithm using SPICE. |
