WebThe voltage between the Base and Emitter ( V BE), is now negative at the Base and positive at the Emitter because for a PNP transistor, the Base terminal is always biased negative with respect to the Emitter. Also the Emitter supply voltage is positive with respect to the Collector ( V CE).So for a PNP transistor to conduct the Emitter is always more positive … WebThe result of a small amount of positive feedback in amplifiers is higher gain, though at the cost of increased noise and distortion. If the amount of positive feedback is large enough however, the result is oscillation, where the amplifier circuit produces its own signal. Using Positive Feedback.
