  • SAR analog-to-digital converter calibration
    Patent number: 11387838
    Abstract: Embodiments of the present disclosure include techniques for calibrating analog-to-digital converters (ADCs), such as successive approximation register SAR ADCs. In one embodiment, a pattern is applied to the input of an ADC to produce digital output codes. Counts of the digital output codes are used detect errors and adjust a clock delay of a comparator in the ADC. In other embodiments, an ADC calibration circuit is coupled to a calibration algorithm executing on a remote server to calibrate one or more ADCs.
