Unformatted text preview: i D , there are two solutions to the equation for v GS . What determines the correct one? [The solution for which v GS > V TO .] (b) The gatesource loop bias equation for the MOSFET is V GG − V SS = V GS + I D R SS . When it is used with the equation in part (a), show that this equation leads to a quadratic equation that must be solved for I D . You do not have to solve the quadratic equation. I D R SS + 1 √ K p I C − ( V GG − V SS − V TO ) = 0 1...
