Abstract

This contribution will present a fully automated approach for explorative topology synthesis of small analog circuit blocks. Circuits are composed from a library of basic building blocks. Therefore, various algorithms are used to explore the entire design space, even allowing to generate unusual circuits. Correct combination of the basic blocks is accomplished through generic electrical rules, which ensure the fundamental electrical functionality of the generated circuit. Additionally, symmetry constraints are introduced to narrow the design space, which leads to more reasonable circuits. Further a replaceable bias-voltage generator is included into the circuit to replicate real world circumstances. For the first evaluation and selection of best candidate circuits, fast symbolic analysis techniques are used. The final sizing is done through a parallelized industrial based sizing method. Experimental results show the feasibility of this synthesis approach.
