A transistor that uses an electric field on a region within the semiconductor in order to block or allow conduction.
(FET) A voltage controlled transistor in which the source to drain conduction is controlled by gate to source voltage.
A three or more terminal transistor that consists of a channel and gate(s). At one end of the channel there is an electrode called the source, into which majority carriers flow from an external circuit. At the other end of the channel there is an electrode, called the drain, out of which electrons flow into the external circuit. Application of a voltage between the third terminal, known as the gate, and the source, establishes an electric field in the channel that changes the resistance between the source and drain, thereby changing the current that flows through the channel. In some FET's, there is another gate terminal which is independent of the first gate terminal.
transistor that makes use of the field established in a p-type channel semiconductor material to control the flow of current through the channel.
A bipolar transistor used as a current amplifying device.
a transistor that uses an electric field to accumulate or deplete a channel region to block or allow conduction.
A transistor consisting of a gate, source, and drain. The voltage applied to the gate controls the conductivity of the channel between the source and drain. Examples of FETs are the MOSFET, JFET
The field-effect transistor (FET) is a transistor that relies on an electric field to control the shape and hence the conductivity of a 'channel' in a semiconductor material. FETs are sometimes used as voltage-controlled resistors. The concepts related to the field effect transistor predated those of the bipolar junction transistor (BJT).
