Body Effect

The body effect explains the changes in the threshold voltage through the change in the source-bulk voltage, approximated by the subsequent equation:

In which VTN is the threshold voltage with substrate bias present, and VTO is the zero-VSB value of threshold voltage, γ is the body effect parameter, and 2φ is the surface potential parameter.

The body can be functioned as a second gate, and is sometimes considered to as the "back gate"; the body effect is sometimes known as the "back-gate effect".
