Threshold Voltage in MOSFET Formulas

Threshold Voltage is the minimum gate-to-source voltage required in a MOSFET to turn it "on" and allow a significant current to flow. And is denoted by V_T. Threshold Voltage is usually measured using the Volt for Electric Potential. Note that the value of Threshold Voltage is always negative.
