OFFSET COMPENSATED ANALOG-TO-DIGITAL CONVERTER

Abstract: an oversampling analog-to-digital converter (adc) may include a quantizer that adds an offset error to each oversampling sample. if not reduced, the offset error may limit the performance of the adc. the existing methods to eliminate the offset may increase a circuit size and slow the operation of the adc. an oversampling adc that can reduce, or remove, the offset error is disclosed. the disclosed adc can be small and fast and still remove the offset. accordingly, the disclosed adc may be used in high performance applications, such as a high-speed image sensor.
