Abstract

The use of the wavelet network for ADC modelling is proposed in the paper. In particular, an original technique is set up capable of identifying the domain of each mother wavelet involved and establishing a compact and complete training set. Moreover, to reduce the complexity of the architecture of the wavelet network and its learning stage, the initialisation is based on the evaluation of all voltage values related to the transitions of the ADC. The technique is applied to a simulated ADC as well as an actual ADC, and several tests are carried out both in the time and frequency domain. The obtained results highlight the advantages of the proposed model if compared to those granted by a neural network-based model.
