Hello everyone! I am trying to design a flash ADC converter that measures voltage from 0 to 6 V with near 7-bit precision (my school assignment requires me to display the result on a 2 digit display : 01 to 99). I have a general idea about the theory behind parallel conversion of voltage, but I still struggle to make the circuit work. My final goal is to cascade around 10 of these converter blocks, which consist of 10 comparators(9 for the second digit and the last for the first digit). But before that I need to make the display work, as the BCD converted data doesn't show up properly. Please advise. I am new to electronics, so feel free if you have any other advice regarding this circuit.
