I have to design two opamp's in cadence that i will be using in my masters project(16 bit Delta sigma ADC) in 90nm\displaystyle ...As far as i know till now, opamp's used in converters should be Low i/p noise, faster settling and High GainBandwidth product, Low offset voltage....are there any more considerations to be considered while designing opamp for delta-sigma ADC...Can u guys refer me any particular configuration of opamp like two stage cascode with Gain boosting and should opamp be fully differential...
