enhancement mode field-effect transistor
Quick Summary
An enhancement-mode field-effect transistor (FET) is a type of transistor that operates by enhancing a region to conduct electricity. Unlike depletion-mode FETs, enhancement-mode FETs are normally switched off and require a voltage applied to the gate to turn them on.1
There are two main types:
* n-type enhancement-mode FET: Made from n-type material separated by p-type material. A positive gate voltage attracts electrons, creating a conductive n-type channel and allowing current to flow.1
* p-type enhancement-mode FET: Made from p-type material separated by n-type material. A negative gate voltage is required to turn it on.1
Metal-oxide-semiconductor field-effect transistors (MOSFETs) are a common type of enhancement-mode FET, widely used in integrated circuits due to their ability to be scaled down, low power consumption, and simpler processing.23
