Cascading Op Amp

  1. Sep 18, 2009 #1
    Hello. I'm looking for someone having practical experience of cascading video amp like NE592 or LM733 in order to get wide bandwidth and huge gain.

    With huge gain can come huge noise. What is the application? What are your target specs?

    And with huge gain and wide bandwidth can come oscillations.

    Hi. I know that for noise and possible oscillations. My target is BW >= 10 MHz, Av >= 10^^6. I already saw with 2 Ic's cascaded, and I just want to know if someone has really tested with 3 or more pcs.

    What's "3 or more pcs"? And if you "know" about the feedback oscillation issue, what is your plan to avoid the oscillations?
