Assignee: TEXAS INSTRUMENTS INCORPORATED
Field: Basic communication processes (Electrical engineering)
Classification: CPC H | IPC H

Claim 1:
2. The ADC of claim 1, wherein the set of comparators is a first set of comparators, the calibration circuitry includes a second set of comparators, each comparator of the second set of comparators having a first input, a second input and an output, the second set of comparators configured to:
receive the analog signal at each respective first input of each comparator of the second set of comparators;
receive at the second input for each comparator of the second set of comparators a respective reference threshold; and
provide comparison results at each output of each comparator of the second set of comparators based on the analog signal and the respective reference thresholds,
wherein the calibration circuitry is configured to determine that the analog signal is proximate to one of the respective reference thresholds of the first set of comparators when the comparison results of the first set of comparators differ from comparison results of the second set of comparators.
