Abstract:For the structural and mathematical features of some scaling fractal fractance approximation circuits,the irregular scaling equations of the typical scaling circuits have been solved and trimmed. Accurate zeropole values are computed by using the transmission matrix algorithm and the matrix labority. It is found and verified the linear distribution rule for the zerpole value which locates in the middle of the circuit section. Not only the linear distribution formula of zeros and poles are given, but also the irregular scaling equations corresponding to the typical scaling fractal fractance approximation circuits have been solved and sorted.
