MOSFET Threshold Voltage Calculator
Calculate threshold voltage considering the body effect
Formula: $V_t = V_{t0} + \gamma \left(\sqrt{2\phi_f + V_{SB}} - \sqrt{2\phi_f}\right)$
Where $V_{t0}$ is zero-bias threshold voltage, $\gamma$ is body-effect parameter, $\phi_f$ is surface potential, and $V_{SB}$ is source-body voltage.
