First, a methodology to automatically generate all analog circuit topologies containing two or three transistors is developed. For each topology, circuit characteristics, such as DC voltage gain, are calculated. The DC voltage gain of each generated circuit is maximized by formulating and solving an optimization problem. After solving the optimization problem, it is shown that over 5,000 out of 56,000 circuits can achieve a DC voltage gain higher than 1. All generated circuit topologies and corresponding characteristics are stored in a database. A GUI is developed to help analog circuit designers search the database and find new topologies. In order to demonstrate the capability of ADA in generating new topologies, a previously unknown high-gain amplifier is selected, and designed in a 0.13-um standard CMOS technology.engUniversity of Calgary graduate students retain copyright ownership and moral rights for their thesis.
