ABSTRACT:
An analog-to-digital converter of the type using a plurality of voltage comparators, each, in response to an applied reference voltage and an analog voltage to be digitized, producing one of two logic signals depending on which of the applied voltages is the greater includes apparatus for altering the reference voltages on some but not all the comparators as a function of time in response to a control signal.
In one embodiment, each of the altered reference voltages is limited to some preselected differential relative to that applied to one of the comparators which does not have its reference voltage altered as a function of time.
In another embodiment, that one comparator has its reference voltage altered as a function of ratio of the time it produces one of the two logic signals relative to the other.
