Body effect of mosfet
WebThe body effect refers to the changes in the threshold voltage by the change in V_{SB}, the source-bulk voltage. Because the body influences the threshold voltage (when it is not tied to the source), it can be thought of as a second gate, and is sometimes referred to as the "back gate"; the body effect is sometimes called the "back-gate effect". WebNov 17, 2015 · The source to body voltage has an direct effect on the threshold of the MOSFET. The relation between the two is given by the Shichman-Hodges model as So, …
