Audio transformers optimization by means of evolutionary algorithms

Unfortunately, complex transformer design problems causes that transformers are not common in audio circuits design except professional devices. This happens partly for their physical construction disadvantages as bulky dimensions and relatively high price and partly because of the fact that designers tend to overlook them even if their employment is reasonable because their design is not trivial. However, in some cases using the transformer can simplify the circuit and improve its noise parameters. In order to make the audio transformer design easier the authors of this paper are developing progressive methods to enable the computer-aided transformer design. One of these methods is based on employing the evolutionary algorithms. In this paper the transformer optimisation by means of Differential evolution is described.
