Abstract
An analog-to-digital converter (ADC) circuit including error correction circuitry for correcting offset drifts in an ADC, such as a successive approximation register (SAR) ADC. The offset drifts can be reduced, such as by sampling the offset following an analog-to-digital conversion and subsequently providing an error correction signal based on the sampled offset.
