Common base type of a transister

  1. Oct 9, 2016 #1
    what happens in the common base type of a transister,if we interchange the input to output and output to input?

    i suppose that the current gain >1 .so this would use for amplification.....

    Using a model for the common base topology: https://en.wikipedia.org/wiki/Common_base

    Perform a small signal analysis, but with the collector driven, and calculate how much signal will appear at the emitter.
