Abstract
A method for calibrating analog-to-digital conversion includes converting, by an analog-to-digital converter (ADC), a first input voltage to a first digital code. The first input voltage is generated from a reference voltage used as a reference voltage by the ADC. The method includes converting, by the ADC, a second input voltage to a second digital code. The second input voltage is generated from the reference voltage used as the reference voltage by the ADC. The method also includes calculating a calibration factor based on the first digital code, the second digital code, the first input voltage, and the second input voltage, converting, by the ADC, a third voltage to a third digital code, and correcting the third digital code using the calibration factor.
