In this study, an unconditionally stable finite difference time domain algorithm for time domain analysis of the active multiconductor transmission lines is presented. The results of the proposed algorithm are compared with the results of the conventional algorithm. While the results of the proposed algorithm have a very good accuracy, the CPU time of the proposed algorithm is less than (about 90%) that of the conventional one. The amplification matrixes of the proposed and conventional algorithms are extracted and numerical stability of them are investigated. The spectral radius of the presented algorithm is smaller than one for any temporal step sizes and the proposed algorithm is unconditionally stable.
