Abstract

Recent work has demonstrated that genetic programming can automatically create both the topology (graphical structure) and sizing (numerical component values) for analog electrical circuits merely by specifying the circuit's high level behaviour (e.g., its desired or observed output, given its input). This automatic synthesis of analog circuits is accomplished using only tools for the analysis of circuits (e.g., a circuit simulator) and without relying on any human know-how concerning the synthesis of circuits. This paper applies genetic programming to the automatic synthesis of five analog and mixed analog-digital circuits that duplicate the functionality of circuits patented after January 1, 2000. The five automatically created circuits read on some (but not all) of the elements of various claims of the patents involved (and therefore do not infringe). The described method can be used as an automated invention machine either to produce potentially patentable new circuits or to engineer around existing patents.
