ugb model of opamp
hi all,
I'm trying to design a low power opamp using gm/id approach.
When i calculated gm/Id according to desired specs. I was arround 380. But normally gm/Id lies between 0 to 29 for a transistor.
I don'n know what to do with this.
Is there any method which convert(by some way) this high value of Gm/Id = 380 to some value which will be included in Current Density Plot of the transistor, so that corrosponding normalized current can be calculated from the graph.
Do u have any comment.........
Thanks...........:?
