Hi, aaron_do: The meaning of that I mentioned before is if an amplifier is high gain, such as more than 100dB, these amplifiers may be desinged by applying cascaed techniques, such as chopper or chopper-stabilized, these techniques usually need higher level and robust compensation techniques such as nested-miller frequency compensation ,NMC ,MNMC...etc. By using that techniques, the dominant-pole is much lower than a gerneral operational amplifier, usually, affter compensation, the dominat-pole may not appear in positive spectrum, because it move to negative-frequency axis by milller pole-splitting theorem. Have a nice day~
