This paper introduces a methodology for symbolic pole/zero extraction based on the
formulation of the time-constant matrix of the circuits. This methodology incorporates
approximation techniques specifically devoted to achieve an optimum trade-off between
accuracy and complexity of the symbolic root expressions. The capability to efficiently
handle even large circuits will be demonstrated through several practical circuits.
