ok so for the power supply of an ADC most of them are 3.3 and 1.8V. but why? why not 1.9V? why not 2.0V? why 1.8V? i dont understand.
I am trying to design a comparator for SA-ADC. if my Vdd is 1.8V and Vss = 0 = gnd, how is the minimum input common mode range be enough? I mean I need something that can be as low as -0.5V assuming the input range if 1V, from 0 to 1V.
