Abstract

This paper presents a method for characterizing the DC operating points of analog circuits. We construct fuzzy DC equations that model circuit parameter variations and apply a global optimization algorithm to estimate the location of DC points. We applied our method to analyze the stability of a ring oscillator and the influence of the input voltage offset on the DC characteristic of a differential pair. Our results prove the effectiveness of our method in describing circuits DC performance parameters and predicting possibilities of undesired circuit operations.
