DEFINITION

Classification: 327/209

Including enhancement and depletion devices:

(under subclass 208) Subject matter including (a) an FET device which permits current conduction by attracting majority carriers to a channel by an appropriate applied voltage and (b) an FET device which inhibits current conduction by repelling majority carriers away from a channel by an appropriate applied voltage.
