Title: How to graph an 3-bit flash ADC transfer curve?
Post by kanishxmas on Apr 12^th, 2018, 8:04pm

Hello All,

Is there a way to graph an ADC transfer curve in cadence? I am feeding my ADC with a differential AC signal and feeding my comparator output into an octal-binary encoder. I am wondering if there is a way to graph in such a way that the curve ends up resembling the ideal ADC transfer curve?
I'd like to know whether it makes sense to even input an AC signal for the purposes of generating the graph? If not, what signal can I use?

Thanks!
