Hi, I have been working on this project ....
Let me describe the circuit so far...
This is kind of load transient tester by linear...
I am developing the similar electric load...but with capability of higher slew rate and high current at low voltage...
at least 5[A/us], at 0.5 [volt] and current of 22[A] at the same condition...
I have been able to estimate that the current as high as 22[A], at 0.5[V] is possible...from the calculation and the simulation....
Now I want to find the stability of the circuit...is the slew rate able to met...do i find the stability by finding the transfer function ?? or is there is any other method...Help please!!

I want some guidelines and tips...or similar examples...
 

break the loop at the gate of Q1 NMOS transistor, then do loop analysis check the loop gain and phase margin
