See discussion on body effect … WebA MOSFET is a four-terminal device having source (S), gate (G), drain (D) and body (B) terminals. In general, The body of the MOSFET is in connection with the source terminal thus forming a three-terminal device such as a field-effect transistor. MOSFET is generally considered as a transistor and employed in both the analog and digital circuits.

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".

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.
