Ask about simulation using pspice

  1. Mar 2, 2012 #1
    1. The problem statement, all variables and given/known data
    Simulate the circuit from 10Hz to 10MHz.
    Produce the Bode Plot for the amplifier output (across RL).
    From the Bode plot, determine the following:
    i) Maximum gain, A(max)
    ii) The cut-off frequency, fc.
    iii) The frequency at the unity gain.

    2. The attempt at a solution
    the maximum gain and cut-off frequency i obtained from the graph,but what is the mean by frequency at the unity gain?

    That should be the frequency where Vout = vs. That is, where the gain of the circuit drops to 1.

    then the answer is like the graph below?
    when vout=vs=1v

    I suppose that would be it (It's hard to make out the detailed contents of the image with its faint lines and lettering on a black background).
