Abstract
A fast acting polarity detector uses a “very fast” polarity detector in tandem with a “precise” polarity detector to increase the maximum speed achievable from an A/D converter that employs a 1-bit folding front end. The fast polarity detector is a coarse polarity detector that immediately controls the 1-bit folder. The precise polarity detector operates more slowly, but more accurately. When the output of the precise polarity detector becomes available, it overrides the output of the fast polarity detector. This process does not limit the speed of the A/D conversion even though the precise polarity detector is slower to operate since the signal levels are small.
