Field-effect transistors (FETs) are semiconductor devices that control the flow of current by applying an electric field, making them essential components in modern electronics for amplifying or switching signals. Their operation is based on the modulation of charge carriers in a channel, which is controlled by a voltage applied to a gate terminal, offering high input impedance and low power consumption.

Field-effect Transistors

Semiconductor devices are essential components in modern electronics, enabling the control and manipulation of electrical signals in devices ranging from smartphones to computers. Their unique properties, derived from the behavior of charge carriers in semiconductor materials, allow them to function as diodes, transistors, and integrated circuits, which form the backbone of digital technology.

Flow of current

An electric field is a vector field around a charged particle that represents the force exerted on other charges placed within the field. The strength and direction of the electric field are determined by the magnitude and sign of the charge, as well as the distance from the charge.

A gate terminal is a critical infrastructure component in the liquefied natural gas (LNG) supply chain, serving as a point where LNG is received, stored, and regasified before being distributed to the natural gas network. It plays a vital role in energy security and market flexibility by allowing imports from diverse global sources and enabling efficient energy distribution to meet fluctuating demand.

High Input Impedance

Low power consumption refers to the design and operation of devices and systems that use minimal energy to perform their functions, thereby extending battery life and reducing energy costs. It is crucial in the development of sustainable technologies and is a key consideration in the design of electronic devices, data centers, and communication networks.
