Transient Analysis of Circuits Including Frequency-Dependent Components Using Transgyrator and Convolution

摘要

A practical method for the transient analysis of circuits including frequency-dependent components, as well as the implementation of the method in a circuit-simulation software package called APLAC, has been presented. The main differences between the method and those previously presented are that the authors introduced the transgyrator and that the authors carefully minimized the number of mathematical operations needed in the analysis. These improvements finally make the method practical for usage in a circuit simulation software package intended for engineers. The implementation of the method in APLAC, using the NPort component model, consists of two separate 'C' programming language source code files, together amounting to only 16 kB. Due to the object-oriented nature of all components written for APLAC, the coding time of the implementation was reduced considerably.
