  2. Biasing - Wikipedia

    en.wikipedia.org/wiki/Biasing

    The operating point of a device, also known as bias point, quiescent point, or Q-point, is the DC voltage or current at a specified terminal of an active device (a transistor or vacuum tube) with no input signal applied. A bias circuit is a portion of the device's circuit that supplies this steady current or voltage.

  3. Bipolar transistor biasing - Wikipedia

    en.wikipedia.org/wiki/Bipolar_transistor_biasing

    A load line diagram, illustrating an operating point in the transistor's active region.. Biasing is the setting of the DC operating point of an electronic component. For bipolar junction transistors (BJTs), the operating point is defined as the steady-state DC collector-emitter voltage and the collector current with no input signal applied.

  4. Bipolar junction transistor - Wikipedia

    en.wikipedia.org/wiki/Bipolar_junction_transistor

    A bipolar transistor allows a small current injected at one of its terminals to control a much larger current between the remaining two terminals, making the device capable of amplification or switching. BJTs use two p–n junctions between two semiconductor types, n-type and p-type, which are regions in a single crystal of material.

  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 ...

  6. Multi-threshold CMOS - Wikipedia

    en.wikipedia.org/wiki/Multi-threshold_CMOS

    One method of creating devices with multiple threshold voltages is to apply different bias voltages (Vb) to the base or bulk terminal of the transistors. Other methods involve adjusting the gate oxide thickness, gate oxide dielectric constant (material type), or dopant concentration in the channel region beneath the gate oxide.

  7. Heterojunction bipolar transistor - Wikipedia

    en.wikipedia.org/wiki/Heterojunction_bipolar...

    A heterojunction bipolar transistor (HBT) is a type of bipolar junction transistor (BJT) that uses different semiconductor materials for the emitter and base regions, creating a heterojunction. The HBT improves on the BJT in that it can handle signals of very high frequencies, up to several hundred GHz .

  8. Bias tee - Wikipedia

    en.wikipedia.org/wiki/Bias_tee

    A bias tee is a three-port network used for setting the DC bias point of some electronic components without disturbing other components. The bias tee is a diplexer.The low-frequency port is used to set the bias; the high-frequency port passes the radio-frequency signals but blocks the biasing levels; the combined port connects to the device, which sees both the bias and RF.

  9. Safe operating area - Wikipedia

    en.wikipedia.org/wiki/Safe_operating_area

    The reverse bias safe operating area (or RBSOA) is the SOA during the brief time before turning the device into the off state—during the short time when the base current bias is reversed. As long as the collector voltage and collector current stay within the RBSOA during the entire turnoff, the transistor will be undamaged.
