One of the key issues in manufacturing of sub-ranging analog-to-digital converters (ADCs) is the necessity to provide high precision of internal amplifiers gain values. The paper proposes two methods of reduction of the influence of amplifiers gain setting errors on the performance of adaptive cyclic ADCs (ACADCs), with and without their postproduction adjustment. The use of the proposed methods allows to significantly weaken the requirements to accuracy of amplifiers and to reduce complexity and sizes of ACADCs and their manufacturing costs. Effectiveness of the developed methods was examined in simulation experiments.
