gate region (1) (of an IGFET)

A control region that determines the surface charge-carrier concentration in the channel region as a function of the gate voltage.

NOTE This definition applies for the actual operating mode of the device regardless of the name of any associated terminal.

(2) (of a JFET): A control region that determines the cross-sectional area of the channel region as a function of the gate voltage.

NOTE This definition applies for the actual operating mode of the device regardless of the name of any associated terminal.

(3) (of a thyristor): A control region in which a momentary injection of controlling charge causes a regenerative turn-on action.

NOTE This definition applies for the actual operating mode of the device regardless of the name of any associated terminal.
