    en.wikipedia.org/wiki/Electronic_circuit

    The basic components of analog circuits are wires, resistors, capacitors, inductors, diodes, and transistors. Analog circuits are very commonly represented in schematic diagrams , in which wires are shown as lines, and each component has a unique symbol.

  3. 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.

  4. Transistor - Wikipedia

    en.wikipedia.org/wiki/Transistor

    A transistor is a semiconductor device used to amplify or switch electrical signals and power. It is one of the basic building blocks of modern electronics. [1] It is composed of semiconductor material, usually with at least three terminals for connection to an electronic circuit.

  5. Field-effect transistor - Wikipedia

    en.wikipedia.org/wiki/Field-effect_transistor

    Cross-sectional view of a MOSFET type field-effect transistor, showing source, gate and drain terminals, and insulating oxide layer. The field-effect transistor (FET) is a type of transistor that uses an electric field to control the current through a semiconductor. It comes in two types: junction FET (JFET) and metal-oxide-semiconductor FET ...

    Figure 1: Basic N-channel JFET common-source circuit (neglecting biasing details). Figure 2: Basic N-channel JFET common-source circuit with source degeneration. In electronics, a common-source amplifier is one of three basic single-stage field-effect transistor (FET) amplifier topologies, typically used as a voltage or transconductance amplifier.

  7. Unijunction transistor - Wikipedia

    en.wikipedia.org/wiki/Unijunction_transistor

    The schematic diagram symbol for a unijunction transistor represents the emitter lead with an arrow, showing the direction of conventional current when the emitter-base junction is conducting a current. A complementary UJT uses a p-type base and an n-type emitter, and operates the same as the n-type base device but with all voltage polarities ...

  8. Safe operating area - Wikipedia

    en.wikipedia.org/wiki/Safe_operating_area

    Illustration of safe operating area of a bipolar power transistor. Any combination of collector current and voltage below the line can be tolerated by the transistor. SOA is usually presented in transistor datasheets as a graph with V CE (collector-emitter voltage) on the abscissa and I CE (collector-emitter current) on the ordinate ; the safe ...

  9. ISFET - Wikipedia

    en.wikipedia.org/wiki/ISFET

    It is a special type of MOSFET (metal–oxide–semiconductor field-effect transistor), [1] and shares the same basic structure, but with the metal gate replaced by an ion-sensitive membrane, electrolyte solution and reference electrode. [2] Invented in 1970, the ISFET was the first biosensor FET (BioFET). The schematic view of an ISFET.
