  2. Audio power amplifier - Wikipedia

    en.wikipedia.org/wiki/Audio_power_amplifier

    Audio stereo power amplifier made by McIntosh The internal view of a Mission Cyrus 1 Hi Fi integrated audio amplifier (1984) [1]. An audio power amplifier (or power amp) amplifies low-power electronic audio signals, such as the signal from a radio receiver or an electric guitar pickup, to a level that is high enough for driving loudspeakers or headphones.

    The driver ADP3418 chip (bottom left), used for driving high-power field transistors in voltage converters. Above it is seen next to such a transistor (06N03LA), probably driven by that driver. In electronics , a driver is a circuit or component used to control another circuit or component, such as a high-power transistor , liquid crystal ...

  4. Line driver - Wikipedia

    en.wikipedia.org/wiki/Line_driver

    A line driver is an electronic amplifier circuit designed for driving a load such as a transmission line. The amplifier's output impedance may be matched to the characteristic impedance of the transmission line. Line drivers are commonly used within digital systems, e.g. to communicate digital signals across circuit-board traces and cables. [1]

  5. Bridged and paralleled amplifiers - Wikipedia

    This should mean that the current draw stays within the limits of the amplifier design. In this scenario, the power delivered by the bridged amplifier pair will be twice the power delivered by a single amplifier channel. [5] However, in some scenarios, amplifiers are designed specifically to operate in bridge mode.

  6. Doherty amplifier - Wikipedia

    en.wikipedia.org/wiki/Doherty_amplifier

    The Doherty amplifier is a modified class B radio frequency amplifier invented by William H. Doherty of Bell Telephone Laboratories Inc in 1936. Whereas conventional class B amplifiers can clip on high input-signal levels, the Doherty power amplifier can accommodate signals with high peak-to-average power ratios by using two amplifier circuits within the one overall amplifier to accommodate ...

  7. Williamson amplifier - Wikipedia

    en.wikipedia.org/wiki/Williamson_amplifier

    The Williamson amplifier is a four-stage, push-pull, Class A triode-output valve audio power amplifier designed by D. T. N. Williamson during World War II. The original circuit, published in 1947 and addressed to the worldwide do it yourself community, set the standard of high fidelity sound reproduction and served as a benchmark or reference ...

  8. Class-T amplifier - Wikipedia

    en.wikipedia.org/wiki/Class-T_amplifier

    Two Tripath chipset Class T stereo amplifier modules. TA2024 6+6W to the left, TA2020 20+20W to the right. Class T was a registered trademark for a switching (class-D) audio amplifier, used for Tripath's amplifier technologies (patent filed on Jun 20, 1996). Similar designs have now been widely adopted by different manufacturers.

    Gash states that they could provide the power to activate the reactor, and Dr. M2 realizes that everyone's combined power could repair it. As Dr. M2 floats in the sky in the core of his castle, the four demons cast a series of spells to channel power into the reactor, ending with Kiyomaro casting Gash's most powerful spell, Baou Zakeruga, to ...
