    Self-biasing of a transistor.

    I know all the types of bias except self bias. I need the circuit for self-biasing of a transistor.


    Thank you.

    Re: Self-biasing of a transistor.

    Related to BJT, the term is usually referring to a common emitter stage with a single bias resistor between collector and base terminal.

    Re: Self-biasing of a transistor.

    not all transistors can be biased using self bias

    JEFT can be biased using self bias
    also Depletion MOSFET can be biased using this technique

    Your post shows, that self-biasing isn't a clearly defined term. You'll find different meanings in literature. That's the problem with this kind of questions.

    Re: Self-biasing of a transistor.

    Exactly ...."Self Bias" as a term is general

    but it is acceptable for simplicity that some types need to be biased (any biasing techniques) so that it works correctly
    for example E-Mosfet needs the gate voltage high enough in order to build channel (i.e. referred to as Threshold voltage )
