How to set up GTL Ref Values for 45nm & 65nm

[CryptiK]

Your algebra is wrong there in the first part. You lost the negative sign with the Y... it should be +36mV, not negative.

I have way oversimplified this for ease of explanation. The answer is in fact -36mv for the 0.667x Y value, but I was debating about how to show that. I thought the way I wrote it showed more clearly what had to be done rather than be mathematically perfect.

This is correct mathematically, but I thought having '+Y' in both equations may confuse people:

Equation:

Vtt x 0.667 + Y = Vtt x 0.635

1.14v x 0.667 + Y = 1.14v x 0.635
0.760v + Y = 0.724v
Y = 0.724v - 0.760v
Y = -0.036v
Y = -36 mv

I have changed it now in the first post.
