    In the voltage amplifier attached, if d = √1+2KRs(VIn - VT). write an algebraic expression for the small signal gain vo/vi in terms of RL, Rs and d.

    vo/vi = -K (VIn - VT) RL
    d = √1+2KRs(VIn - VT)
    d^2 = 1+2KRs(VIn - VT)
    (VIn - VT) = (d^2-1)/2KRs
    vo/vi = - RL * (d^2-1) / 2Rs

    Is my answer correct?

    Why did you make your schematic in a Word Text Document instead of as an image?
    Please post it as a GIF or PNG image.
