Comparator offset cancellation in a successive approximation analog-to-digital converter |
摘要 |
A successive approximation analog-to-digital converter (ADC) includes an adjustable voltage source that applies an adjustable voltage to an input of a comparator of the ADC to cancel an offset of the ADC. The ADC also includes a control that suspends adjustments of the adjustable voltage when the adjustable voltage converges on the offset. The adjustable voltage source is a digital-to-analog converter.
