The MOSFET (metal–oxide–semiconductor field-effect transistor) is a type of insulated-gate field-effect transistor (IGFET) that is fabricated by the controlled oxidation of a semiconductor, typically silicon. The voltage of the covered gate determines the electrical conductivity of the device; this ability to change conductivity with the amount of applied voltage can be used for amplifying or switching electronic signals. The MOSFET is the basic building block of most modern electronics, and the most frequently manufactured device in history, with an estimated total of 13 sextillion (1.3 × 1022) MOSFETs manufactured between 1960 and 2018. It is the most common semiconductor device in digita…

In electronics, the metal–oxide–semiconductor field-effect transistor (MOSFET, MOS-FET, MOS FET, or MOS transistor) is a type of field-effect transistor (FET), most commonly fabricated by the controlled oxidation of silicon. It has an insulated gate, the voltage of which determines the conductivity of the device. This ability to change conductivity with the amount of applied voltage can be used for amplifying or switching electronic signals. The term metal–insulator–semiconductor field-effect transistor (MISFET) is almost synonymous with MOSFET. Another near-synonym is insulated-gate field-effect transistor (IGFET). Physicist Julius Edgar Lilienfeld first proposed the concept of a field-eff…

An insulated-gate bipolar transistor (IGBT) is a three-terminal power semiconductor device primarily forming an electronic switch. It was developed to combine high efficiency with fast switching. It consists of four alternating layers (NPNP) that are controlled by a metal–oxide–semiconductor (MOS) gate structure. Although the structure of the IGBT is topologically similar to a thyristor with a "MOS" gate (MOS-gate thyristor), the thyristor action is completely suppressed, and only the transistor action is permitted in the entire device operation range. It is used in switching power supplies in high-power applications: variable-frequency drives (VFDs) for motor control in trains, electric ca…

The field-effect transistor (FET) is a type of transistor that uses an electric field to control the current through a semiconductor. It comes in two types: junction FET (JFET) and metal–oxide–semiconductor FET (MOSFET). FETs have three terminals: source, gate, and drain. FETs control the current by the application of a voltage to the gate, which in turn alters the conductivity between the drain and source. FETs are also known as unipolar transistors since they involve single-carrier-type operation. That is, FETs use either electrons (n-channel) or holes (p-channel) as charge carriers in their operation, but not both. Many different types of field-effect transistors exist. Field-effect tran…

High-Output-Current Boron-Doped Single-Crystal Diamond MOSFETs with a Thin Boron-Doped Epitaxial Layer.. High-output-current boron-doped diamond (B-diamond) metal-oxide-semiconductor field-effect transistors (MOSFETs) with a modulated boron-doped epitaxial layer were fabricated. An intrinsic diamond epitaxial layer was deposited on the single-crystal diamond substrate as a buffer layer, and plasma-enhanced chemical vapor deposition (PECVD) SiO 2 was employed as both the gate dielectric and passivation layer. The boron-doped epitaxial layer has a thickness of approximately 500 nm and a boron concentration in the range of 10 17 -10 18 cm -3 . The B-diamond MOSFETs showed clear p-channel opera…

Study of n-Channel 4H-SiC MOSFETs with a High-<i>k</i>/SiO<sub>2</sub> Stacked Gate Dielectric and a p<sup>+</sup>-Polysilicon Gate.. In this study, n-channel 4H-SiC MOSFETs with a high- k /SiO 2 stacked gate dielectric and a p + -polysilicon gate are proposed and investigated via numerical simulations. The high- k dielectric increases the gate capacitance, thereby reducing the specific on-state resistance of the devices. The p + -polysilicon increases the work-function difference between the gate and the surface p-SiC, which compensates for the threshold voltage reduction caused by the high- k dielectric. Simulation results demonstrate that replacing the…

A transistor is a semiconductor device used to amplify or switch electrical signals and power. It is one of the basic building blocks of modern electronics. It is composed of semiconductor material, usually with at least three terminals for connection to an electronic circuit. A voltage or current applied to one pair of the transistor's terminals controls the current through another pair of terminals. Because the controlled (output) power can be higher than the controlling (input) power, a transistor can amplify a signal. Some transistors are packaged individually, but many more in miniature form are found embedded in integrated circuits. Because transistors are the key active components in…

A class-D amplifier, or switching amplifier, is an electronic amplifier in which the amplifying devices (transistors, usually MOSFETs) operate as electronic switches, and not as linear gain devices as in other amplifier classes. Class-D amplifiers operate by rapidly switching back and forth between the power supply rails, using pulse-width modulation, pulse-density modulation, or related techniques to produce a pulse train output. Little energy is dissipated in the amplifying transistors because they are always either fully on or fully off, so efficiency can exceed 90%. A low-pass filter is typically used to attenuate the pulse train output high-frequency content to reduce quiescent current…

The junction field-effect transistor (JFET) is one of the simplest types of field-effect transistor. JFETs are three-terminal semiconductor devices that can be used as electronically controlled switches or resistors, or to build amplifiers. Unlike bipolar junction transistors, JFETs are exclusively voltage-controlled in that they do not need a biasing current. Electric charge flows through a semiconducting channel between source and drain terminals. By applying a reverse bias voltage to a gate terminal, the channel is pinched, so that the electric current is impeded or switched off completely. A JFET is usually conducting when there is zero voltage between its gate and source terminals. If…

Defect-mediated generation-recombination dynamics governing conductance response in floating-body transistors.. As CMOS technologies evolve toward ultra-thin floating-body architectures, defect-mediated carrier dynamics increasingly dominate device behavior, challenging conventional linear interpretations of electrical response in nanoscale transistors. In this work, we demonstrate that the conductance response of foundry-fabricated floating-body transistors is governed by generation-recombination (GR) dynamics associated with deep-level defects inside the ultra-thin silicon body. Frequency-dependent conductance measurements reveal bell-shaped responses that exhibit weak gate-bias dependenc…

An experimental investigation of unique high stepup boost converter for electric vehicle and solar photovoltaic.. High step-up DC–DC converters are essential in electric vehicle (EV) and photovoltaic (PV) applications, where low-voltage inputs must be efficiently boosted to higher levels. Conventional converters suffer from high switching losses, bulky components, and unstable regulation under dynamic conditions. To address these challenges, this paper proposes a compact transformer based high step-up boost (HGB) converter integrated with an SG3525 PWM controller and an analog proportional–integral (PI) compensation network. The novelty of the design lies in the jointly optimized transforme…
