MOSFETThe metal-oxide-semiconductor field-effect transistor (MOSFET, MOS-FET, or MOS FET) 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. A metal-insulator-semiconductor field-effect transistor (MISFET) is a term almost synonymous with MOSFET.
Voltage dividerIn electronics, a voltage divider (also known as a potential divider) is a passive linear circuit that produces an output voltage (Vout) that is a fraction of its input voltage (Vin). Voltage division is the result of distributing the input voltage among the components of the divider. A simple example of a voltage divider is two resistors connected in series, with the input voltage applied across the resistor pair and the output voltage emerging from the connection between them.
Gain (electronics)In electronics, gain is a measure of the ability of a two-port circuit (often an amplifier) to increase the power or amplitude of a signal from the input to the output port by adding energy converted from some power supply to the signal. It is usually defined as the mean ratio of the signal amplitude or power at the output port to the amplitude or power at the input port. It is often expressed using the logarithmic decibel (dB) units ("dB gain").
RS-232In telecommunications, RS-232 or Recommended Standard 232 is a standard originally introduced in 1960 for serial communication transmission of data. It formally defines signals connecting between a DTE (data terminal equipment) such as a computer terminal, and a DCE (data circuit-terminating equipment or data communication equipment), such as a modem. The standard defines the electrical characteristics and timing of signals, the meaning of signals, and the physical size and pinout of connectors.
Id Softwareid Software LLC (ɪd) is an American video game developer based in Richardson, Texas. It was founded on February 1, 1991, by four members of the computer company Softdisk: programmers John Carmack and John Romero, game designer Tom Hall, and artist Adrian Carmack. id Software made important technological developments in video game technologies for the PC (running MS-DOS and Windows), including work done for the Wolfenstein, Doom, and Quake franchises at the time.
RS-485RS-485, also known as TIA-485(-A) or EIA-485, is a standard, originally introduced in 1983, defining the electrical characteristics of drivers and receivers for use in serial communications systems. Electrical signaling is balanced, and multipoint systems are supported. The standard is jointly published by the Telecommunications Industry Association and Electronic Industries Alliance (TIA/EIA). Digital communications networks implementing the standard can be used effectively over long distances and in electrically noisy environments.
Small-signal modelSmall-signal modeling is a common analysis technique in electronics engineering used to approximate the behavior of electronic circuits containing nonlinear devices with linear equations. It is applicable to electronic circuits in which the AC signals (i.e., the time-varying currents and voltages in the circuit) are small relative to the DC bias currents and voltages. A small-signal model is an AC equivalent circuit in which the nonlinear circuit elements are replaced by linear elements whose values are given by the first-order (linear) approximation of their characteristic curve near the bias point.
SchutzstaffelThe Schutzstaffel (SS; also stylized as ᛋᛋ with Armanen runes; ˈʃʊtsˌʃtafl̩; Protection Squadron) was a major paramilitary organization under Adolf Hitler and the Nazi Party in Nazi Germany, and later throughout German-occupied Europe during World War II. It began with a small guard unit known as the Saal-Schutz ("Hall Security") made up of party volunteers to provide security for party meetings in Munich. In 1925, Heinrich Himmler joined the unit, which had by then been reformed and given its final name.
Waffen-SSThe Waffen-SS (ˈvafn̩ʔɛsˌʔɛs) (Armed SS) was the combat branch of the Nazi Party's paramilitary Schutzstaffel (SS) organisation. Its formations included men from Nazi Germany, along with volunteers and conscripts from both occupied and unoccupied lands. The Waffen-SS grew from three regiments to over 38 divisions during World War II, and served alongside the German Army (Heer), Ordnungspolizei (Order Police), and other security units.
École Polytechnique Fédérale de LausanneThe École polytechnique fédérale de Lausanne (EPFL; English: Swiss Federal Institute of Technology in Lausanne; Eidgenössische Technische Hochschule Lausanne) is a public research university in Lausanne, Switzerland. Established in 1853, EPFL has placed itself as a university specializing in engineering and natural sciences. EPFL is part of the ETH Domain, which is directly dependent on the Federal Department of Economic Affairs, Education and Research.
Allgemeine SSThe Allgemeine SS (ˌalɡəˈmaɪ̯nə ˈɛs ˈɛs; "General SS") was a major branch of the Schutzstaffel (SS) paramilitary forces of Nazi Germany; it was managed by the SS Main Office (SS-Hauptamt). The Allgemeine SS was officially established in the autumn of 1934 to distinguish its members from the SS-Verfügungstruppe (SS Dispositional Troops or SS-VT), which later became the Waffen-SS, and the SS-Totenkopfverbände (SS Death's Head Units or SS-TV), which were in charge of the Nazi concentration camps and extermination camps.
Id Techid Tech is a series of separate game engines designed and developed by id Software. Prior to the presentation of the id Tech 5-based game Rage in 2011, the engines lacked official designation and as such were simply referred to as the Doom and Quake engines, from the name of the main game series the engines had been developed for. "id Tech" has been released as free software under the GNU General Public License. id Tech versions 0 to 3 were released under GPL-2.0-or-later. id Tech versions 3.5 to 4.
