Abstract
Quasi-differential successive-approximation methods and structures are provided for converting analog signals into corresponding digital signals. These methods and structures realize the signal-to-noise improvements of fully-differential SAR ADCs and the calibration accuracy improvements of pseudo-differential SAR ADCs. Structures of the invention operate in a fully-differential mode to establish more-significant bits of the corresponding digital signals and in a pseudo-differential mode to establish the less-significant bits.
