    I should design an opamp transimpedance amplifier as homework, but i
    have some doubts:
    1) if current signal is an impulse (of positive value) generated every
    10ms (for example), is it right to put the first pole of open loop
    gain at frequency higher than (1/10)KHz?Or i shoud put the first pole
    at frequency higher than 10(1/10)KHz (so the phase margin is equal to
    180°)? I'm interested on voltage output (bacause this should be read
    by an ADC)...
    2)If i want to design an opamp with single supply, other problems
    (respect to bipolar supply) are present or not?
    Thanks

    Me, too. We generally don't do homework unless you pay the current
    engineering rate (approx. $160.00/hr.).

    Good Luck!

    Yeah, but with specifications delivered like those, you wouldn't take
    the contract. This may be an ESL issue, but I think the customer
    doesn't know what he wants.
