Compensating signal generators for self-calibrating multi-bit signal tracking ADC, based on inaccurate DAC with weight redundancy

Abstract

The possibility of constructing a generator of compensating signal for self-calibrating multi-bit signal tracking ADC, based on inaccurate DAC with weight redundancy are analyzed. Two possible approaches: with construction of the digital part of the generator solely based on the binary system, and with the use of additional nodes on the basis of systems with weight redundancy are suggested. The methods of structural and functional organization of the compensating signal generator based on inaccurate DAC with weight redundancy within the proposed approaches are considered in the paper.
