Electrical characteristics of MOSFETs (Static Characteristics Vth)

Electrical characteristics of MOSFETs (Static Characteristics Vth)

Gate threshold voltage (Vth)

Vth stands for "threshold voltage." Vth is the gate voltage that appears when the specified current flows between source and drain.

Vth measurement

Gate-source voltage, VGS, is increased until drain current, ID, reaches the specified value, at which point VGSis measured.
