Precise Algorithms for Pole-Zero Analysis inElectronic circuit DesignJosef Dobe s , Dalibor Biolek , Jan M chal , David Cern y , and Libor Sl ama Czech Technical University in Prague, Department of Radio Engineering, Technick a 2, 16627 Praha 6, Czech Republic Brno University of Technology, Department of Microelectronics, Udoln 53, 60200 Brno, Czech RepublicAbstract The Pole-Zero Analysis is generally known to be verysensitive to the numerical precision of the computer arithmetics. In thepaper, various methods are suggested for solving that problem. First,an optimal pivoting strategy of the algorithm that reduces the generaleigenvalue problem to the standard one is presented for both full-and sparse-matrix procedures.
