WebWhat is the biasing of PN junction? Bias. A diode (PN junction) in an electrical circuit allows current to flow more easily in one direction than another. Forward biasing means putting … WebD implies the diode biasing voltage. When the diode is in forward bias, or V D>0 V, then the voltage drop ˚ j across the junction, or between the two regions decreases, because ˚ j= V 0 +V R. The depletion region becomes smaller and the current ow becomes larger across the pnjunction. When the diode is reverse biased, then ˚ j becomes larger ...
