hey i am designing a high gain opamp with BJTS, using a bipolar supply..
cn anyone help me in wat stages i should divide ths in order to achieve the reqd output???
the input frequency is to b kept 100kHz and the open loop gain must, at least, be 100..

You mean the open loop gain must be 100 at a frequency of 100KHz, for a GBWP of 10MHz? That should be doable, even with off the shelf BJTs, though you will probably need fast devices or some clever design (cascodes, gain boosting, etc).
Is this a design for an ASIC, or are you building this as a discrete circuit on a PCB/breadboard?
