channel region (1) (of an IGFET)

A control region through which the principal current passes and in which the concentration of principal-current charge carriers is determined by voltage applied to a gate, the principal current being the result of an applied drift field.

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 through which the principal-current charge carriers pass and whose cross-section is determined by the voltage applied to a gate, the principal current being the result of an applied drift field.

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