Body effect in mosfet
WebDetailed Solution. Body effect refers to the change in the transistor threshold voltage (VT) resulting from a voltage difference between the transistor source and body. Because the voltage difference between the source and body affects the VT, the body can be thought of as a second gate that helps determine how the transistor turns on and off. Webanomalous phenomena such as kink effect, drain current overshoot, single transistor latch and reduced drain breakdown voltage make it difficult to apply SOI MOSFET to VLSI circuits [7]. These problems are originated basically from the floating body in SOI MOSFET and can be eliminated with stabilized body potential. In general, two
