Hi, I want to design an ADC with these specifications: Fin = 20MHz BW= 20MHz ENOB > 4 Power consumption P < 1mW Could anyone suggest me some ADC for this kind? I have searched a lot in IEEE but there are only two ADC with SAR ADC and time-interleaved ADC. The ultralow power consumption makes it hard for me to find a architecture. I have little experience about this. Kindly help me.
