Figure 3-54C.Effects of bias on N-channel depletion MOSFET.
Figure 3-55 (view A, view B, and view C) illustrates the effect of forward bias on an enhancement
mode N-channel MOSFET. In this case, a positive voltage applied to the gate increases the width of the
current channel and the amount of drain current (ID).
