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?
