ENEE 313 Notes Prof. Neil Goldsman. Threshold voltage is the voltage applied between gate and source of a MOSFET that is needed to turn the device on for linear and saturation regions of operation. The following analysis is for determining the threshold voltage of an N-channel MOSFET (also called an N-MOSFET).

TH ) ( 1 + λV ) DS. • The original observation that the current is constant in the saturation region is not quite correct. The end point of the channel actually moves toward the source as V D increases, increasing ID. Therefore, the current in the saturation region is a weak function of the drain voltage.

A MOSFET is a type of transistor which commonly has three terminals. Like its peers, it is used for the switching and amplification of electrical signals. Like many electrical and electronic components, MOSFETs have many important characteristics that determine how it operates. One of these characteristics is the Threshold Voltage (Vth).
