The synthesis of analog circuits assuming a hypothetical intrinsic evolutionary integrated
hardware platform containing only CMOS transistors is examined. It is shown that to
efficiently synthesize analog circuits both topology and transistors sizing should be treated
separately. To this end a flexible chromosome coding scheme able to generate the most
common analog building blocks and the inclusion in the genetic algorithm of a separate
transistor sizing step are proposed.
