- Abstract:
- In analog-to-digital converters (ADCs), dynamic and memory nonlinear effects can contribute simultaneously to the distortion of the digitised signal. These effects can be modelled and compensated effectively via Volterra filters. The paper deals with a Volterra filter for ADC error correction based on an inverse model. An easy-to-implement correction technique, based on a efficient mathematical model of Volterra filter designed to reduce burden in model definition, in filter identification, and in experimental calibration is proposed. Preliminary simulation and experimental results for integrating ADCs highlight the effectiveness of the proposed modelling and correction approach.
