Solve the previous two results for iDS. You will get a quadratic equation, and you will have to choose the correct root: make sure that iDS=0 when vIN=VT. What is your solution for iDS?

PLEASE PLEASE PLEASE WHATS THE EQUATION ..AFTER A HELL LOT OF EFFORT I HAD REACHED TO (vIN-VT)/RS + (1/K*RS^2) *(1-sqrt(1+2*K*RS*(vIN-VT))) BUT THATS A CROSS.... PLEASE ANYONE....
