  2. Operational amplifier - Wikipedia

    en.wikipedia.org/wiki/Operational_amplifier

    These op amps were effectively small circuit boards with packages such as edge connectors. They usually had hand-selected resistors in order to improve things such as voltage offset and drift. The P45 (1961) had a gain of 94 dB and ran on ±15 V rails. It was intended to deal with signals in the range of ±10 V. 1961: A varactor bridge op amp.

  3. CMOS amplifier - Wikipedia

    en.wikipedia.org/wiki/CMOS_amplifier

    CMOS amplifiers (complementary metal–oxide–semiconductor amplifiers) are ubiquitous analog circuits used in computers, audio systems, smartphones, cameras, telecommunication systems, biomedical circuits, and many other systems. Their performance impacts the overall specifications of the systems.

    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 ...

    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.

  6. Electronic kit - Wikipedia

    en.wikipedia.org/wiki/Electronic_kit

    An electronic kit is a package of electrical components used to build an electronic device. Generally, kits are composed of electronic components, a circuit diagram (schematic), assembly instructions, and often a printed circuit board (PCB) or another type of prototyping board. There are two types of kits. Some build a single device or system.

  7. Current-mode logic - Wikipedia

    en.wikipedia.org/wiki/Current-mode_logic

    The fast operation of CML circuits is mainly due to their lower output voltage swing compared to the static CMOS circuits, as well as the very fast current switching taking place at the input differential pair transistors. One of the primary requirements of a current-mode logic circuit is that the current bias transistor must remain in the ...

  8. Bootstrapping (electronics) - Wikipedia

    en.wikipedia.org/wiki/Bootstrapping_(electronics)

    In the sense used in this paragraph, bootstrapping an operational amplifier means "using a signal to drive the reference point of the op-amp's power supplies". [5] A more sophisticated use of this rail bootstrapping technique is to alter the non-linear C/V characteristic of the inputs of a JFET op-amp in order to decrease its distortion. [6] [7]

  9. Current mirror - Wikipedia

    en.wikipedia.org/wiki/Current_mirror

    An explanation follows of how the circuit in Figure 3 works. The operational amplifier is fed the difference in voltages V 1 − V 2 at the top of the two emitter-leg resistors of value R E. This difference is amplified by the op amp and fed to the base of output transistor Q 2.
