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


Thank you.
 

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

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.
 

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 )
