how to calculate amps
Good luck, if you don't make the circuit simpler. I've done a telescopic (without the Gain Boosters), and I used the matlab symbolic tool box. This was a transfere function, big very big. So I would sugest, reduce the circuit to its important parts (like input pair and input cascode). And claime that the PMOS side can be designed with the same speed, the pmos side introduces a pole zero and can be around the seconde pole (NOMS cascode).
