    i need to design an op- amp for a 10 bit adc.
    the expected gain of the ADc is about 80 DB.The first stage is a folded cascoded and the 2nd stage stage is class AB.Input voltage :1 vpp. design is to be done for 1.8 V supply voltage.someone please help me..

    Maxim for one has several opp amps that work down to 1.8V.

    I would advise you not to try to get all 80dB of gain out of one stage.
