Dear Tosei, Jerry,
Thanks for your replies.
Tosei: I think you are assuming leakage from one terminal to bulk. I am looking at caps which are leaky from terminal to terminal, i.e. the cap actually has some finite shunt resistance in parallel. Otherwise, your suggestion would work.
Jerry: I thought of this too. I think this falls in the same category as the Ahuja compensation. I did not try it out because I could not see how the Miller compensation would work correctly still. Of course, the DC behavior would be much improved due to the additional source follower, and if one is lucky, then the impedance presented by the Miller cap is much smaller than the parallel shunt resistance (to be expected) in the critical frequency range around the unity-gain crossover. Will try it out, although I may have found an alternate solution in form of a dense enough cap which leaks only from one end to the ground instead of carrying a shunt resistance. I can then connect the leaky end to the opamp output as Tosei suggests.
Best regards,
Vivek
