Abstract
Techniques are described that can be used to extract an offset and a gain of a signal chain, which can be used for digital correction of an analog-to-digital converter (ADC) output to help achieve a life time and temperature stable ADC output. For example, using various techniques, a value for a voltage reference VREF and a value for ground (GND) (or other reference voltage) can be converted, which can then be used to determine gain and offset, respectively, of the signal chain.
