Self-calibratable Adaptive Sub-ranging ADC Insensitive to Amplifiers Gain Errors

Konrad Jędrzejewski, Łukasz Małkiewicz
Abstract:
The paper proposes a variant of adaptive sub-ranging ADC capable of self-calibration in presence of the internal amplifiers gains deviations due to technological imperfections. The changes needed to be implemented to make the adaptive ADC insensitive to gains errors, and the procedure of self-calibration that uses the internal DAC as calibration signal source, are proposed. Capabilities of the approach are discussed on the basis of results of computer simulations.
