Abstract
A system and apparatus for reducing the effects of circuit mismatch in analog-to-digital converters is disclosed. In one form, an analog-to-digital converter (ADC) includes a switching network operable to couple an analog input received by a sample and hold module to a folding amplifier operable to process the analog input. The ADC further includes an averaging resistive network coupled to the folding amplifier and operable to provide an output representative of a portion of the analog input received by the folding amplifier to produce a digital representation of the analog input.
