ANALOG-TO-DIGITAL CONVERTER DIFFERENTIAL NONLINEARITY ERROR CORRECTION IN BUILDING CONDUCTANCE HISTOGRAMS
Journal Title: Metrology and Measurement Systems - Year 2006, Vol 13, Issue 2
Abstract
In nanowire electrical conductance quantization studies, conductance histograms are built from a large number of conductance curves of conductance stepwise variations in time. The conductance curves are obtained by means of a digital oscilloscope; as each digital oscilloscope has an analog-to-digital converter (ADC) whose differential nonlinearity (DNL) error strongly affects the obtained conductance histograms. The effect of the DNL error can be corrected through the procedure described in this paper. Moreover, measurement results of the DNL error for three digital oscilloscope models and the long-term DNL error variations for one oscilloscope model are presented.
