CE amplifier - How to limit bandwidth?

  1. Apr 17, 2013 #1
    When using the CE BJT amplifier configuration, when a shunt capacitor is placed across the collector resistor, how does this act as a bandwidth limiting cap?

    Two questions to help you answer the question yourself:

    What happens to the amplifier gain when you change the collector impedance?
    What happens to the impedance of C5 at high frequencies?

    I see. Thank you very much for that. I did not think about the affect on RC and the associated gain.
