  2. JFET - Wikipedia

    en.wikipedia.org/wiki/JFET

    Following Shockley's theoretical treatment on JFET in 1952, a working practical JFET was made in 1953 by George C. Dacey and Ian M. Ross. [4] Japanese engineers Jun-ichi Nishizawa and Y. Watanabe applied for a patent for a similar device in 1950 termed static induction transistor (SIT). The SIT is a type of JFET with a short channel. [4]

  3. Depletion and enhancement modes - Wikipedia

    en.wikipedia.org/wiki/Depletion_and_enhancement...

    The mode can be determined by the sign of the threshold voltage (gate voltage relative to source voltage at the point where an inversion layer just forms in the channel): for an N-type FET, enhancement-mode devices have positive thresholds, and depletion-mode devices have negative thresholds; for a P-type FET, enhancement-mode have negative ...

  4. Field-effect transistor - Wikipedia

    en.wikipedia.org/wiki/Field-effect_transistor

    The JFET (junction field-effect transistor) uses a reverse biased p–n junction to separate the gate from the body. The static induction transistor (SIT) is a type of JFET with a short channel. The DEPFET is a FET formed in a fully depleted substrate and acts as a sensor, amplifier and memory node at the same time.

  5. Threshold voltage - Wikipedia

    en.wikipedia.org/wiki/Threshold_voltage

    The threshold voltage, commonly abbreviated as V th or V GS(th), of a field-effect transistor (FET) is the minimum gate-to-source voltage (V GS) that is needed to create a conducting path between the source and drain terminals. It is an important scaling factor to maintain power efficiency.

  6. Multigate device - Wikipedia

    en.wikipedia.org/wiki/Multigate_device

    FlexFET is a planar, independently double-gated transistor with a damascene metal top gate MOSFET and an implanted JFET bottom gate that are self-aligned in a gate trench. . This device is highly scalable due to its sub-lithographic channel length; non-implanted ultra-shallow source and drain extensions; non-epi raised source and drain regions; and gate-last fl

  7. Discrete complementary JFETS - Wikipedia

    en.wikipedia.org/wiki/Discrete_complementary_JFETS

    Improved JFET process technologies, discrete JFET devices and JFET topologies will continue to challenge highly integrated monolithic designs for sockets in high quality electronic products. The primary reasons are cost and customization. Costs are too high for integrated circuit companies to integrate customized high-performance for niche ...

  8. Common source - Wikipedia

    en.wikipedia.org/wiki/Common_source

    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. The easiest way to tell if a FET is common source, common drain, or common gate is to examine where the signal enters and leaves. The remaining terminal is ...

  9. LSK489 - Wikipedia

    en.wikipedia.org/wiki/LSK489

    The LSK489 is a monolithic N-Channel JFET designed and built by Linear Integrated Systems, Inc.LIS Inc, a Fremont, CA company.The part was introduced in 2013 [1] [2] and was named by EDN Tech as one of the “2013 EDN Hot 100” electronics industry innovations for the year. [3]
