Abstract

This paper describes a unified approach to the approximate symbolic analysis of large linearized analog circuits. It combines two new approximation-during-computation strategies with a variation of the classical two-graph tree enumeration method. The first strategy is to generate common trees of the two-graphs, and therefore the product terms in the symbolic network function, in the decreasing order of magnitude. The second approximation strategy is the sensitivity-based simplification of two-graphs, which excludes from the two-graphs many circuit elements that have little effect on the network function being derived. Our approach is therefore able to symbolically analyze much larger analog integrated circuits than previously reported, using complete small signal models for the semiconductor devices. We show accurate yet reasonably sized symbolic network functions for integrated circuits with up to 39 transistors whereas previous approaches were limited to less than 15.
