ALGORITHM FOR EFFICIENT SYMBOLIC ANALYSIS OF LARGE ANALOG CIRCUITS

An algorithm is presented that generates simplified symbolic expressio ns for the small-signal characteristics of large analogue circuits. Th e expressions are approximated while they are computed, so that only t he most significant terms are generated which remain in the final expr ession. This principle leads to dramatic savings in CPU time and memor y compared to existing techniques, significantly increasing the maximu m size of circuits that can be analysed. By taking into account a rang e for the value of a circuit parameter rather than one single number t he generated symbolic expressions are also generally valid.
