The threshold voltage can be increased if the source is not connected to the body terminal. The threshold voltage is. V T = V T 0 + γ 2 ϕ + V S B − γ 2 ϕ. where V T 0 is the threshold voltage when the source-to-body V S B = 0, and γ and ϕ are device parameters. If the NMOS source is connected to ground and so is the body then V S B ... WebSep 26, 2014 · One way is to eliminate the common substrate completely, as is done in Silicon On Insulator (SOI). Another way to do it is to have the NFET inside a well. This can be done in a process where a N-type buried layer (or tub) is added to provide an isolation well. There are probably other ways to attack the problem as well. fnc reviews
