ABSTRACT:
An A/D converter which utilizes a plurality of series connected stages is disclosed. Each stage produces a single digital output bit. Errors are dynamically compensated utilizing alignment cycles. Error correction circuitry statistically analyzes an alignment signal during an alignment cycle. Various feedback paths form within each stage during an alignment cycle, and error compensation signals achieve optimum values which compensate for errors within each stage.
