Hi Vinay !
This a very generic question.
1. You need the specs for your Flash ADC 2. I don't know whether you are doing this work just to get your chip nicely framed in the hallway of your Uni or to get it really on silicon. In the latter case, you need to choose the right process and technology node that are likely to get your specs realistic. This is a very important point for industrial prodcution. May be not that important for a PHD dissertation.
Well the next steps are pretty much simple: 1. You may then need to have a high level model for your ADC. You can use system level tools like Matlab/simulink or a behavioral model like Verilog-A, Verilog-AMS, etc ... 2. Once you have proved the functionality, you can then tackle the designing of the IC building blocks in a tool like Cadence DFII. You may need a PDK to get your ADC running on a real process as explained above. All what you need at this stage is puting the right components together, run transitor level simulations ... etc.
I think this is enough to keep you busy for the first couple of years. You may come back afterwards for the rest of the story, i.e. layout, DRCs, LVS, post layout sims ... etc.
Assuming I have understood your question. As per the ADC flash itself, just look at the books ...
Cheers, Riad.
