Precise Algorithms for Pole-Zero Analysis in Electronic Circuit Design
Original language description
The pole-zero analysis is generally known to be very sensitive to the numerical precision of the arithmetics. Various methods are suggested for solving that problem. First, an optimal pivoting strategy of the algorithm that reduces general eigenvalue problem to the standard one is presented for both full and sparse-matrix procedures. The algorithm increases the precision of the semisymbolic analysis, especially for the large-scale radio frequency circuits. A novel technique is also incorporated recognizing multiple poles or zeros, which are often computed inaccurately by standard algorithms. A new type of this procedure called secondary root polishing is also described. The accuracy is furthermore increased using longer numerical data. First, the longdouble precision is used. Further, a novel application of a suitable multiple-precision arithmetic library is suggested. Finally, using the longer numerical data to eliminate possible imprecision of the multiple eigenvalues is evaluated.
