  2. Chip tuning - Wikipedia

    en.wikipedia.org/wiki/Chip_tuning

    Cars with a turbo fitted can have the requested and allowable boost levels raised, these applications usually have the most effect if the turbo fitted is a low pressure turbo which leaves the most room for improvement. Another reason to change the electronic control unit map is if there are engine, intake, or exhaust modifications to the car.

  3. Automotive electronics - Wikipedia

    en.wikipedia.org/wiki/Automotive_electronics

    The earliest electronic systems available as factory installations were vacuum tube car radios, starting in the early 1930s.The development of semiconductors after World War II greatly expanded the use of electronics in automobiles, with solid-state diodes making the automotive alternator the standard after about 1960, and the first transistorized ignition systems appearing in 1963.

    Please help to improve this article by introducing more precise citations. ( June 2020 ) ( Learn how and when to remove this message ) Transistor aging (sometimes called silicon aging ) is the process of silicon transistors developing flaws over time as they are used, degrading performance and reliability, and eventually failing altogether.

    It is used in switching power supplies in high-power applications: variable-frequency drives (VFDs) for motor control in electric cars, trains, variable-speed refrigerators, and air conditioners, as well as lamp ballasts, arc-welding machines, photovoltaic and hybrid inverters, uninterruptible power supply systems (UPS), and induction stoves.

  6. Hot-carrier injection - Wikipedia

    en.wikipedia.org/wiki/Hot-carrier_injection

    The term "hot electron" comes from the effective temperature term used when modelling carrier density (i.e., with a Fermi-Dirac function) and does not refer to the bulk temperature of the semiconductor (which can be physically cold, although the warmer it is, the higher the population of hot electrons it will contain all else being equal).

  7. High-electron-mobility transistor - Wikipedia

    The invention of the high-electron-mobility transistor (HEMT) is usually attributed to physicist Takashi Mimura (三村 高志), while working at Fujitsu in Japan. [4] The basis for the HEMT was the GaAs (gallium arsenide) MOSFET (metal–oxide–semiconductor field-effect transistor), which Mimura had been researching as an alternative to the standard silicon (Si) MOSFET since 1977.

  9. Saturation velocity - Wikipedia

    en.wikipedia.org/wiki/Saturation_velocity

    When this happens, the semiconductor is said to be in a state of velocity saturation. [2] Charge carriers normally move at an average drift speed proportional to the electric field strength they experience temporally. The proportionality constant is known as mobility of the carrier, which is a material property.
