WebN channel JFET consists of an n-type bar at the sides of which two p-type layers are doped. The channel of electrons constitutes the N channel for the device. Two ohmic contacts are made at both ends of the N-channel device, which … WebJan 22, 2014 · A JFET is a P-N junction. Normally, reverse-biasing this P-N junction is what results in the high gate impedance. If you reverse bias it enough, the depletion region extends all the way across the channel, turning the transistor off. Review the basic physical structure of a P-channel JFET: Just an N-type gate stuck in a P-type channel.
