Hi i want to add noise to the input current source of my multiplier circuit and i want to run the DC analysis. Can anyone tell me can is there any noise file already written that i can obtain from cadence or do it have to write a file of my own and include the txt file. Also once obtained can anyone pls tell me how to include it. In the current source i am only getting option to enter the "name" and"value". How can i define the path from wer the noise file should be included. Thank you!!!

Hi i found online that there were 2 ways to add noise to current source. One was to include a noise txt file and 2nd was to manually mention the noise/freq pairs. I mentioned 5 pairs of freq and noise values to the current source.
Freq, Noise
9999.999999999871, 2.687817570986485e-12
10232.92992280741, 2.663957372134177e-12
10471.28548050886, 2.640415064596976e-12
10715.19305237592, 2.617187240308667e-12
10964.78196143171, 2.59427052569283e-12
For the dc analysis of the multiplier circuit i get a linear output of Iout vs Iin. I am getting a linear response but even after including the noise/freq pairs i am getting no change in my output. Can anyone pls tell me wer i am going wrong. Would be really helpful!!! Thank you!!!
