Classification: CPC H | IPC H

Claim 14:
15. The circuit of claim 13, wherein the ADC is a first ADC, the calibration circuitry includes a second ADC in parallel with the first ADC, the second ADC includes the second set of comparators, and the offset error is estimated as: offset error=E(y1,prbs=1)−E(y1,prbs=−1), where E(y1,prbs=1) is the expectation or mean in the digital output code of the first ADC for the analog signal when the PRBS value=1, and E(y1,prbs=−1) is the expectation or mean in the digital output code of the first ADC for the analog signal when the PRBS value=−1.
