    Circuit diagram symbol for a representative op amp. Pins are labeled as listed above. An operational amplifier (often op amp or opamp ) is a DC-coupled electronic voltage amplifier with a differential input , a (usually) single-ended output, [ 1 ] and an extremely high gain .

  3. Widlar current source - Wikipedia

    en.wikipedia.org/wiki/Widlar_current_source

    The Widlar circuit may be used with bipolar transistors, MOS transistors, and even vacuum tubes. An example application is the 741 operational amplifier, [4] and Widlar used the circuit as a part in many designs. [5] This circuit is named after its inventor, Bob Widlar, and was patented in 1967.

  4. Circuit diagram - Wikipedia

    en.wikipedia.org/wiki/Circuit_diagram

    A circuit diagram (or: wiring diagram, electrical diagram, elementary diagram, electronic schematic) is a graphical representation of an electrical circuit. A pictorial circuit diagram uses simple images of components, while a schematic diagram shows the components and interconnections of the circuit using standardized symbolic representations.

    en.wikipedia.org/wiki/Circuit_topology_(electrical)

    Circuit diagram of a ladder network low-pass filter: a two-element-kind network. Comprehensive cataloguing of network graphs as they apply to electrical circuits began with Percy MacMahon in 1891 (with an engineer-friendly article in The Electrician in 1892) who limited his survey to series and parallel combinations. MacMahon called these ...

  9. Ladder logic - Wikipedia

    en.wikipedia.org/wiki/Ladder_logic

    Part of a ladder diagram, including contacts and coils, compares, timers and monostable multivibrators. Ladder logic is widely used to program PLCs, where sequential control of a process or manufacturing operation is required. Ladder logic is useful for simple but critical control systems or for reworking old hardwired relay circuits. As ...
