Apparatus and method for analyzing circuits using reduced-order modeling of large linear subscircuits

摘要

A circuit analyzer and method are disclosed for generating and outputting a Matrix Pad+E,acu e+EE via Lanczos (MPVL) approximation of a frequency response of a circuit from input circuit parameters. A processing unit has a memory for storing circuit characteristic data representing a circuit; a program for generating matrix transfer function data relating to a matrix transfer function associated with the circuit characteristic data; a processor for executing the program; and the processing unit generates the frequency response signal in response to the matrix transfer function data.
