The math and the model follow each other fairly well. The math was using ß = 93. I think my model uses ß = 125. I expected a little variation because of this.
I assumed a 1k load and used the 4T:14T FT37-61 transformer. The transformer could be adjusted for the desired Zout.
oh wow that is so much better than I expected!!!!
ReplyDeleteI looked at the spice model and found ß = 125. I think you used 97. You are probably closer to the actual. I looked at the datasheet and 125 was on the high end of the range.
