Neglecting the channel-length-modulation effect, show that for the depletion-type NMOS transistor of Fig. P5.67, the i−v relationship is given by i = 1/2 k’n(W/L)(v2 −2Vtv) for v ≥ Vt i = −1/2 k’n(W/L)V2t for v ≤ Vt (Recall that Vt is negative.) Sketch the i−v relationship for the case: Vt = −2 V and k’n(W/L) = 2 mA/V2 .
