FINDING ALL SOLUTIONS OF PIECEWISE-LINEAR RESISTIVE CIRCUITS CONTAINING SOPHISTICATED TRANSISTOR MODELS

An efficient algorithm is presented for finding all solutions of piece wise-linear resistive circuits containing sophisticated transistor mod els such as the Gummel-Poon model or the Shichman-Hodges model. When a circuit contains these nonseparable models, the hybrid equation descr ibing the circuit takes a special structure termed pairwise-separabili ty (or tuplewise-separability). This structure is effectively exploite d in the new algorithm. A numerical example is given, and it is shown that all solutions are computed very rapidly.
