Abstract: In this work, we compare evolutionary algorithms and standard optimisation methods on two circuit design problems: the parameter extraction of a device circuit model and the multiobjective optimisation of an operational transconductance amplifier. The comparison is made in terms of quality of the solutions and computational effort, that is, objective function evaluations needed to compute them. The experimental results obtained show that standard techniques are more robust than evolutionary algorithms, while the latter are more effective in terms of the standard metrics and function calls. In particular for the multiobjective problem, the observed Pareto front determined by evolutionary algorithms has a better spread of solutions with a larger number of non-dominated solutions when compared to the standard multiobjective techniques.
