Hi all
Can anyone tell me how delaying of a clock in a dynamic comparator makes its performance better??
also
How the offset is reduced in a dynamic comparator by delaying the clock???
 

Delayed, relative to what?

If the input signal is "busy" and changing in lockstep
with (say) a sample clock and a time-offset comparator
clock, there is certainly a "sweet spot" that gives you
the best settling time vs sample droop vs max digitization
rate compromise.
