WebAug 12, 2015 · Since a JFET has a PN junction (i.e. a rectifier diode) from gate to channel, it is paramount not to bring this diode into conduction, otherwise the JFET won't work and may also be damaged. Therefore the gate diode must always be reverse biased (or slightly forward biased, but let's not go there for simplicity). WebSelf-Bias: This is the most common FET Biasing Methods. Self-bias for an N-channel JFET is shown in Fig. 13.15. This circuit eliminates the requirement of two dc supplies i.e., only drain supply is used and no gate supply is connected. In this circuit, a resistor R S, known as bias resistor, is connected in the source leg.
