  2. iPhone 7 - Wikipedia

    en.wikipedia.org/wiki/IPhone_7

    The iPhone 7 and iPhone 7 Plus [a] are smartphones that were developed and marketed by Apple Inc. They are the tenth generation of the iPhone.They were announced on September 7, 2016, at the Bill Graham Civic Auditorium in San Francisco by Apple CEO Tim Cook, and were released on September 16, 2016, succeeding the iPhone 6, iPhone 6 Plus, iPhone 6S and iPhone 6S Plus as the flagship devices in ...

    The rear cameras on the 7 and 7 Plus both have an f / 1.8 aperture, as compared to f / 2.2 on the iPhones 6 and 6 Plus, though the 7 Plus' tele camera has f / 2.8 and is not optically stabilized. [26] [64] It also has a brighter quad-LED True Tone flash The 2017 iPhone 8 camera features a larger sensor and a newer color filter.

  4. Backup battery - Wikipedia

    en.wikipedia.org/wiki/Backup_battery

    This is often called the CMOS battery or BIOS battery. The original IBM AT through to the PS/2 range, used a relatively large primary lithium battery, compared to later models, to retain the clock and configuration memory. [2] These early machines required the backup battery to be replaced periodically due to the relatively large power consumption.

  5. List of 4000-series integrated circuits - Wikipedia

    en.wikipedia.org/wiki/List_of_4000-series...

    The following is a list of CMOS 4000-series digital logic integrated circuits.In 1968, the original 4000-series was introduced by RCA.Although more recent parts are considerably faster, the 4000 devices operate over a wide power supply range (3V to 18V recommended range for "B" series) and are well suited to unregulated battery powered applications and interfacing with sensitive analogue ...

  6. CMOS amplifier - Wikipedia

    en.wikipedia.org/wiki/CMOS_amplifier

    CMOS technology was introduced primarily for digital circuit design. In the last few decades, to improve speed, power consumption, required area, and other aspects of digital integrated circuits (ICs), the feature size of MOSFET transistors has shrunk (minimum channel length of transistors reduces in newer CMOS technologies).

  7. CMOS - Wikipedia

    en.wikipedia.org/wiki/CMOS

    CMOS inverter (a NOT logic gate). Complementary metal–oxide–semiconductor (CMOS, pronounced "sea-moss ", / s iː m ɑː s /, /-ɒ s /) is a type of metal–oxide–semiconductor field-effect transistor (MOSFET) fabrication process that uses complementary and symmetrical pairs of p-type and n-type MOSFETs for logic functions. [1]

  8. Nonvolatile BIOS memory - Wikipedia

    en.wikipedia.org/wiki/Nonvolatile_BIOS_memory

    It is referred to as non-volatile memory or NVRAM because, after the system loses power, it does retain state by virtue of the CMOS battery. When the battery fails, BIOS settings are reset to their defaults. The battery can also be used to power a real time clock (RTC) and the RTC, NVRAM and battery may be integrated into a single component.

  9. Flash memory - Wikipedia

    en.wikipedia.org/wiki/Flash_memory

    In 2016, Micron and Intel introduced a technology known as CMOS Under the Array/CMOS Under Array (CUA), Core over Periphery (COP), Periphery Under Cell (PUA), or Xtacking, [60] in which the control circuitry for the flash memory is placed under or above the flash memory cell array. This has allowed for an increase in the number of planes or ...
