Abstract
A method, comprising: receiving an analog input; determining an upper outer rail and a lower outer rail as polling values to be used by voltage comparators; blanking at least three comparators; determining which two of the at least three comparators are closest to the input analog voltage levels; defining the two comparators which are closest to the analog input signal to be the next comparators of the next sampling process; assigning a remaining comparator at a voltage level in between the new top and bottom voltage levels; enabling the outer rails, but blanking the inner rail; progressively narrowing down the voltage range spanned by the two outer comparators; and generating a 2-tuple value of an asynchronous voltage comparator crossing.
