PROGRAMMABLE FRACTIONAL TIME DELAY IN DIGITALLY OVERSAMPLED MICROPHONE SYSTEMS, CIRCUITS, AND METHODS

摘要

Programming time delay data in an oversampled sensor includes determining whether to enter Programming Mode based on a value of a system parameter received by the oversampled sensor. Programming Mode is entered when the value of the system parameter corresponds to Programming Mode, The time delay data is programmed in the oversampled sensor during Programming Mode, The oversampled sensor uses the time delay data to time delay its output in an oversampled domain. Programming Mode is exited after a predetermined time has expired relative to when Programming Mode was entered. The system parameter can be a frequency of a sampling clock signal
