Mathematical proof for positive feedback

  1. Jan 17, 2013 #1
    Is there a mathematical proof that the positive feedback makes the op-amp saturated?

    Do you understand why it saturates (non-mathematical seat of the pants explanation)?

    Let's clarify this by specifying positive DC feedback drives the opamp into saturation. Positive AC feedback makes it oscillate.

    Yes of course
