3 - - ERROR-FEEDBACK THIRD-ORDER DELTA-SIGMA TIME-TO-DIGITAL CONVERTER USING CHARGE PUMP

摘要

An error feedback third-order delta-sigma time-to-digital conversion circuit using a charge pump is disclosed. The time-to-digital converter is a primary time-to-digital converter consisting of a subtractor, a digital to time converter, and an error feedback structure using a quantizer. It consists of a multi-stage noise shaping (MASH) structure.
