Algorithmic analog-to-digital converter with reduced differential non-linearity and method |
摘要 |
An analog to digital converter section for use in an analog to digital converter which includes a converter stage which produces a digital and an residue output. The residue output is applied to an over-range stage which produces a second residue output equal to the first residue output reduced in magnitude by the magnitude of a reference voltage. The over-range stage is capable of operating with a relatively high feedback factor to increase operating speed and with commutated feedback-capacitor switching to reduce differential non-linearity errors.
