Linearity correction is performed by determining whether a data output value (DOUT) from an analog-to-digital converter (ADC) is in a first subrange or a second subrange. If DOUT is in the first subrange, then DOUT is scaled by a first scaling correction factor (SCF), and the result is...
I am using internal ADC of the iMX6UL. It shows a strange non-linearity where the conversion seems to increase the error up to mid scale (where error of conversion is 100mV, huge!) then the error decreases and conversion returns correct values when invput voltge approaches 3V and towards...
Hi, I would like to understand how to correct non-linearity in the output during the calibration of the ADC. As the image shows, how do I perform the
in there linearity. A decoupling cap getting bad and maybe a strong drifting resistor networt can also lead to increasing linearity errors, though this would be a rare case and more like a defect. Ideally the critical points of an ADC are known and a test could concentrate at such critical...

Simulations results for a 14-bit ADC show that a 7-bit linear stimulus with one sample per code can be used to measure the INL of the ADC with a maximum estimation error of 1 LSB. 展开 关键词: Kalman Filtering Analog to Digital Converters (ADC Code Density Testing Samples per code INL...
The servo loop occupies a small area and is suitable for built-in self-test application. The measurement results for DNL and INL are transformed into a digital representation, and the measurement resolution and error are determined by the delay of standard digital gates. Simulation results are ...

Hence, the generated look-up table for an ADC with the worst case DNL error (i.e. largest number of missing codes) can eliminate the missing codes for all other ADCs in the array. The worst DNL errors occur at the major code transitions, such as at ¼ and ½ of the full-scale ...
