METHOD AND SYSTEM FOR SELECTING IMPLEMENTATION OF A FILTER CONTROLLER BETWEEN A SINGLE CONVERSION MODE THAT ENSURES A FULLY-SETTLED CONVERTED OUTPUT AND A CONTINUOUS CONVERSION MODE
A method and system for selecting implementation of a filter controller between a single conversion that ensures a fully-settled converted output and a continuous conversion of an input signal are disclosed. State machine determines whether convert start signal has a duration, which ends on or before a first occurrence of a conversion done on the input signal. Conversion done is an occurrence of when a bit set has been converted from the input signal. If convert start signal has a duration which ends on or before the first occurrence of conversion done, then state machine selects and implements single conversion of the input signal. Digital system ensures a fully-settled converted output by waiting for the filter to receive and filter a predetermined number of bit sets for a conversion output and then outputting the conversion output. Otherwise, state machine selects and implements continuous conversion of the input signal.
