ee.sharif.eduIn the weak inversion, the minority carrier concentration is small, but not zero. Fig. 5 shows the variation of minority carrier concentration along the length of the channel for an n-channel MOSFET biased in the weak inversion region. Let us consider that the source of the n-channel MOSFET is grounded, , and the drain to source voltage V.
