In the following circuit, the nMOS has a threshold voltage of Vr = 1.0 Vand K = 2 mA/VÅlso given that R1 = 3 kNVpp identical with vp. = 0.9(i.e. use CVD model for the diodes). Our task is to set the value of Rp such that the MOSFET will be operating at the edge of saturation. What's edge of saturation? We know in the triode region vps vGs – VrHence, the edge of saturation means when vps = vGS - VAt this mode, both the equations for In in saturation mode and triode mode would give the exact 6 Vand the diodes are same result, VDD VDD Rp R1 KIKKH
