Re: Simulate DNL and INL
pablomilanes, I use AMS simulation. AMS means Analog-Mixed Signal, that is to say Spectre-Verilog simulation. Yes, matlab is used with system simulation. For a top simulation of an ADC, the paramenters needed to simulate are static parameters (INL,DNL,Full Erroe,Offset Error, etc.) and dynamic parameters (SNR,SFDR,THD, etc.).
Karthikeya, "...then the resolution of DAC must be atleast 2-4 bits more than ADC's ..." is due to the accuracy of DAC more than ADC. For example, you
must prove accuracy of a ruler. You can use another ruler whose accuracy is more than the ruler measure it. Do you understand?
