Abstract: A snapout calculator, and wherein the snapout calculator determines where the reference levels for the various comparators shall be placed after each asynchronous sample is generated.

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.

Abstract: An apparatus, comprising: an analog to digital converter including: a clipping detector; and a post-processor, wherein the post processor generates synchronous values of clipped data based on non-clipped values of non-clipped data.

Abstract: A method, comprising: receiving a plurality of 2-tuples of asynchronously sampled inputs at an asynchronous to synchronous reconstructor; performing a coarse asynchronous to synchronous conversion using the plurality of 2-tuples to generate a plurality of low precision synchronous outputs; generating a high precision synchronous output, z0, using a plurality of asynchronous 2-tuples, low precision synchronous outputs after it, and its own high precision outputs from previous steps; calculating c0 and c?1 by summing future low precision outputs and the past high precision outputs after they are weighted with the appropriate windowed sinc. values and then subtracted from appropriate asynchronous samples; calculating, the four quantities “s?11”, “s01”, “s00” and “s?10” based on particular values of the windowed sinc. function; and using c0, c?1, s?11, s01, s00 and s?10, the high precision synchronous output of interest, z0 is generated.
