Electronic modelling using ANNs for analogue and mixed-mode behavioural simulation

We describe the state of the art and some preliminary results obtained by application of artificial neural networks (ANN) to modelling of dynamic non-linear electronic circuits. ANNs are used for application of the black-box modelling concept in the time domain. The ANN´s topology, the testing signal used for excitation, together with the complexity of the ANN is considered. Examples of Pion-linear dynamic modelling are given encompassing a wide variety of modelling problems. Verification of the concept is performed by verifying the ability of the model to generalize i.e. to create acceptable responses to excitations not used during training. Implementation of these models within a behavioural simulator is exemplified.
