Dear all,
Could anyone please help me measure INL of an ADC in cadence? Currently i am giving a ramp input to the ADC, and trying to get the histogram measurement of the ADC output. Using the, I am trying to calculate the DNL and hence INL. I feel that this method is not accurate. I tried using the INL function in cadence. But that didnt work either. Could someone please help me with this.
Thanks.
Sir,
I tried this too. The following is the code that i am using to calculate DNL and i am trying to sum the DNLs up to get INL.
Code:
nbins = 1024;
dnl= hist(y,nbins)/n-1;
I am trying to get the INL of the ADC with 10 bits accuracy. Hence nbins = 1024. Y is the data imported from cadence. But i am unable to find the value of n where n is the number of samples in the bin for an ideal case.
Do you suggest any other method?
