This paper presents a method to speed up the structural synthesis of op-amps presented in . Op-Amp topologies are created, sized and evaluated according to a given set of specifications. Three different types of op-amps are supported: single-output, fully-differential and complementary op-amps. The sizing and evaluation process is parallelized using multi-threading techniques. On a common computer the new algorithm needs less than eight hours to find all suitable topologies for a given set of specifications out of thousands of topologies compared to 22 h in . The experimental results present the speed-up of the algorithm on seven different specification sets.
