Title: Evaluating PSD of Opamp/Data Converter in MATLAB from Cadence Spectre
Post by repah on Sep 10^th, 2017, 2:08pm

Hello,

I am designing various opamps and data converters in Cadence Spectre and would like to use MATLAB to generate Power Spectrum Density (PSD) plots of them.

I do not have the Cadence MATLAB toolbox installed and would like to do this without the toolbox.

Do I expert the traces directly out as .csv files and then process them in MATLAB to generate the associated PSDs ?

Is there another way ? Any direction or help or advice regarding this would be helpful - or a tutorial.

I am designing a Discrete Time Sigma Delta Modulator and would like to check the PSD of my opamps, system simulations of the converter and the transistor level converter also. I am looking to compare the associated PSDs of all of these associated configurations.

Thank you!
