Web• As the drain voltage increases, the reverse bias on the body‐drain PN junction increases, and hence the drain depletion region widens. ÆVTH decreases with increasing drain … WebBody effect - nMOS device Increasing Vsb causes the channel to be depleted of charge carriers and thus the threshold voltage is raised. Change in Vt is given by ΔVt = γ.(Vsb)1/2 where γ is a constant which depends on substrate doping so that the more lightly doped the substrate, the smaller will be the body effect The threshold voltage can ...
http://www-classes.usc.edu/engr/ee-s/477p/s13/asst3soln.pdf In n-channel enhancement-mode devices, a conductive channel does not exist naturally within the transistor, and a positive gate-to-source voltage is necessary to create one such. The positive voltage attracts free-floating electrons within the body towards the gate, forming a conductive channel. But first, enough electrons must be attracted near the gate to counter the dopant ions added to …
