I'm working on a second order switched capacitors sigma-delta modulator,
I want to calculate the SNR of the modulated signal (output of the modulator),
Please can anyone help me how to calculate the SNR of this signal with the calculator of CADENCE,
I do not know how to calculate SNR with cadence.
But in my case, I simulated & extracted data (0,1,0,1,1......) and calculated SNR with MATLAB.
If you want, I can send you my code.
Hello ljy4468
I have find many code that calculate the SNR with MATLAB, but everyone give me a different result compared to others, and I don't know what is the best one.
Please can you send me your code.
Thanks.

Here's how I do it:

P.S. I also dump to Matlab for an FFT. However, I do compute the SNR/SNDR using Cadence Ocean/Skill.
Hello PoojanWagh
I don't find the code of "matpsd" procedure in this skill/ocean code,
please can you send me the code of this procedure,
