Hello ppl,
I could use your opinion on a problem I am facing with my op-amp design. It's single stage folded cascode. Trouble is I'm not able to get the current of 25uA (am getting only 21uA) to flow in the two folded cascode branch.(spice file attached) I have changed the bias voltages and sizes but without an idea of why it's happening, it's hard to troubleshoot!
Second problem is that my DC transfer characteristic seems shifted to the left of the origin (image attached). And I am really concerned if it's something I should be worried about. All help highly appreciated! Thanks in advance!
