The Matlab Toolbox for Simulation Analysis and Design Support of New Adaptive Sub-ranging A/D Converters
Konrad Jedrzejewski
Abstract:
The paper presents the toolbox for simulation analysis and support of the high-level design of new adaptive sub-ranging analog-to-digital (A/D) converters whose digital parts allow the iterative calculation of output codes using digital estimation algorithms. The developed appropriate methods and simulation tools enable the assessment of the converters characteristics taking into consideration many different non-idealities (e.g. offsets, noises, non-linearities, gain mismatches) of the internal components of ADCs. The simulation analysis can support the proper choice of the suitable converter configuration and tuning of parameters of the conversion algorithm, which enables to achieve the best characteristics of the converters under assumed level of errors of the components. The toolbox can be used at initial stages of design of the adaptive sub-ranging A/D converters to preliminary evaluation of the expected performance and its comparison with the performance of the existing comparable sub-ranging A/D converters.
