Field-effect Transistor
A field-effect transistor (FET) is a type of transistor commonly used in space and astronautical engineering applications. It operates by controlling the flow of current through a semiconductor channel using an electric field. FETs are known for their high input impedance, low noise, and low power consumption, making them ideal for use in space-based applications where power and weight are critical factors. There are several types of FETs, including junction FETs (JFETs), metal-oxide-semiconductor FETs (MOSFETs), and insulated-gate FETs (IGFETs). MOSFETs are the most commonly used type of FET in space and astronautical engineering due to their high input impedance and low power consumption. They are used in a variety of applications, including power amplifiers, voltage regulators, and digital logic circuits.
