The
Metal Oxide Semiconductor Field Effect Transistor is based on the original field-effect transistor introduced in the 70s. The invention of the power MOSFET was partly driven by the limitations of bipolar power junction transistors (
BJT's) which, until recently, was the device of choice in many power electronics applications.
An application of MOSFET technology is found in
stereo amplifiers, where almost every manufacturer refers to it as an amazing
rarity. MOS transistors are perfect for providing a high quality amplified electric signal because of their ability to tolerate high
voltage and
current simultaneously. They are also used in a marginally different form in your computer and other consumer electronics.
A
schematic detailing the basic workings of a MOS transistor was created c.1930, but the first one was not practically implemented until mid 1960.
