I m designing ADC,but don't know how simulate SNR,SNDR, and SFDR of ADC with candence.

please help me,thank you!!!! thank you!!!
 

cadence sfdr

Normally, the Matlab tools will be used.
I also don't know how to simulate it in cadence environment.
 

how to simulate snr

Hi

I usually perform these calculations using Matlab.

In cadence you can plot the power spectral density(psd) and measure SFDR.
SNR and SNRD i really don't know how to calculate them in cadence environment.
 

sfdr cadence

How simulation SFDR?please tell me!!!

Click to expand...

Use the DFT, you can find it in calculator toolbox.
setup the start, stop time, internal, window, etc.
you can measure SFDR by max harmonic
