    Hello,

    I made two inverter circuit:
    http://www3.sympatico.ca/captoro/inverter.gif
    My goal is to have about 33-33v in the output to drive some mosfets.
    I am not about which circuit is more stable, the one with OP amp or
    the one below with just the Mosfets.
    The problem with the CMOS inverter is that I need three steps instead
    of two. Mainly because the gate voltage is not high enough, but I
    cannot put it higher then 12v.
    As for the OPAMP circuit, I can use the MC34071 OPAMP which has a max
    of 44v supply.
    Which circuit should I use, or any modification to be done ?

    thanks

    Hi,

    Ok, I modified the circuits, let me know if this is what you meant.
    So the better circuit will be the CMOS gate.

    John,

    I put the OPAMP in parallel, the problem is what you mentioned
    earlier about the slow slew rate.
    Also about the second circuit, I understand about putting them in
    parallel , but I am not sure what you mean by " level shifting for
    the first stage"

    k
