Homework Help: Base collector voltage problem

  1. May 9, 2005 #1
    Please justify this phenomenon:

    In an active mode for a transistor, ideally it is assumed that collector current is independent of the base collector reverse bias, whereas, the collector is slightly dependent on the base collector voltage.

    Thanks

    Sorry...read it again !

    Btw what's the importance of De-Morgan's Law in digital studies?

    Is it because it simplifies the logic ?
    or there's some other reason behind it.

    Please reply to both of my queries.

    Thanks again

    Look at the current vs voltage characteristics of a diode

    It's just because it simplifies the logic, which might lead to fewer circuit elements to achieve the desired effect.
