In case of enhancement n-channel mosfets
Webn and Ln, both in µm, are the channel width and channel length of the MOSFET. If Vtn > 0, the nMOSFET is said to be of the enhancement type; if Vtn < 0, it is said to be of the depletion type. The threshold voltage Vtn depends on the body bias voltage VSB as ( ) Vtn =Vtn0 +γn 2φfn +VSB − 2φfn (4) WebFigure 1 The n-channel enhancement MOSFET construction and circuit symbol. Consider the case when the gate and source terminals are connected to a reference node and the drain terminal is connected to a positive voltage supply V DD, as shown in Figure 2(a). The bulk terminal is also connected to the reference node, by virtue of its connection to the …
