Newbie level 6
i m working on flash adc..........i m using fully differentail topology. i m using sample and hold circuit. my input range is .6 tp - .6(1.2v p to p) nd 3.3v supply. At the o/p of sample nd hold this signal is biased at dc level 1.6v. this o/p goes to diff amplifier where it will be compared with refrence voltage. My question is how to bias the refrence voltage at that particular level. Is there some other tefchnique??
