Abstract: In a method of operating an analog-to-digital converter, a gain error and an offset error that are associated with a digital code generated from the analog-to-digital converter are obtained by performing a first analog-to-digital conversion on a first input analog signal. The gain error and the offset error are stored. A calibration digital code is generated by performing a second analog-to-digital conversion on a second input analog signal based on the gain error and the offset error.
