Hi Sheldon,
Thanks for spending your valuable time and extending a helping hand!
I have tried to contact Jonathan, twice from different email accounts one from a public (yahoo, hotmail, etc) and one private account. Seems the cadence server refused to deliver the email or he is no longer at Cadence.
Incidentally, I did find a white paper in the Cadence website on this topic. And since no author is given but the test bend is the same as is the format of the ocean script, I must conclude it was also from Jonathan. Unfortunately, although it included more ocean script code, it added little to my understanding of my issue.
For those interested,
http://www.cadence.com/whitepapers/FVofDiffOpAmp_wp.pdf I did notice the sub title on Slide 18, and thought that was the issue. However, rehashing the ocean script in my head, running the ocean script, and reading the white paper seems to have confused me more. At the end of the presentation, he attaches the actual plot generated by the ocean script and it appears that he did not modify the gate width, and yet the plot still appears identical to slide 18.
Rgds,
Sam
