Transistor question

  1. Mar 30, 2008 #1
    1. The problem statement, all variables and given/known data

    What does a capacitor across the base and collector of the transistor do? Apparantly adding a cap (1uF) will slow it down. Can anyone explain how?

    2. Relevant equations



    3. The attempt at a solution

    Have you already studied feedback? The capacitor provides a feedback of high frequencies from the collector to the base.

    Can you please elaborate or provide me with a reference. I have a text by Gaussi on Analog devices. What section does this come in (miller capacitance??)

    I don't know your textbook. Miller capacitance is a way of analyzing the effect of the feedback provided by your capacitor.
