Abstract
A SAR ADC is provided with a hybrid offset calibration that includes a digital calibration without bit extension. Due to the lack of bit extension, the digital calibration can only address integer multiples of least-significant bits for the offset. The hybrid offset calibration further includes an analog calibration that addresses a remaining fraction of a least-significant bit of the offset.
