Method of Integral Nonlinearity Testing and Correction of Multi-Range ADC by Direct Measurement of Output Voltages of Multi-Resistors Divider

摘要

There is developed method of testing points generation for identification and correction of integral nonlinearity of high performance ADC. The developed method is based on averaging all voltages of multi-resistors voltage divider. It is investigated influence of resistors' error and random error of ADC on residual error of integral nonlinearity correction for method based on multi-resistor divider.
