Nested Miller Compensated OP-AMPS transfer function.

[Chiranka K]

Hey guys, i was trying to figure out the transfer function of the transconductor given in the figure below, it would be really helpfull if someone either suggested a book where i can find the transfer function, or actually give the solution to it.

.
I did find a transfer fuction, but the bode plot of that tf, gives me infinite Phase Margin.
Thank you.

Why not search for the image and look for ResearchGate? I think 60 deg would be the ideal case.

I remember that Sansen's book has this kind of stuff.
