WebAug 26, 2015 · This refers to the voltage Vds that counteracts the opening of the n-channel (NMOS), at the drain end. Since the width of the channel is a function of Vgs - Vtn, the mosfet saturates (pinches off) when Vds is greater or equal than/to Vgs - Vtn. Pinch off voltage is defined as the gate-to-source voltage at which drain-to-source current is zero. WebIn a long channel MOSFET, the width of the pinch-off region is assumed small relative to the length of the channel. Thus, neither the length nor the voltage across the inversion layer change beyond the pinch-off, resulting in a drain current independent of drain bias. Consequently, the drain current saturates.

WebIf the channel is short enough, Ec will not be able to reach the same peak value as in Fig. 7–5a. As a result, a smaller Vgs is needed in Fig. 7–5d than in Fig. 7–5b to pull the barrier down to 0 eV. In other words, Vt is lower in the short channel device than the long channel device. This explains the Vt roll-off shown in Fig. 7–4.
