WebFixed Bias with Emitter Resistance. It is the modified form of fixed biased circuit where external resistance is connected to the emitter terminal. This circuit requires an extra resistor for emitter which provides negative feedback. The bias voltage V BB-V BE = I B R B + I E R E should appear across RE to set I E ≈I c. WebCathode bias. In electronics, cathode bias (also known as self-bias, or automatic bias) is a technique used with vacuum tubes to make the direct current (dc) cathode voltage positive in relation to the negative side of the plate voltage supply by an amount equal to the magnitude of the desired grid bias voltage.
