Multi-Resistor Voltage Divider

Method of Adc’s Nonlinearity Correction Based on High Voltage Source

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, which is powered by reference voltage source with output voltage higher than range of tested ADC. It is investigated influence of resistors’ error and random error of ADC on residual error of integral nonlinearity correction for proposed method.
