WebFor a PNP BJT sketch qualitatively the minority carrier density in the quasi-neutral regions across the device when it operates in forward active mode. In the plot you must qualitatively indicate and label: a) the edges of the depletion regions, consistently with the properties of each junction. b) the minority carrier concentrations under no ... WebMay 29, 2024 · Why BJT is minority carrier device? By design, most of the BJT collector current is due to the flow of charge carriers (electrons or holes) injected from a heavily doped emitter into the base where they are minority carriers that diffuse toward the collector , and so BJTs are classified as minority-carrier devices. WebThis device is an NPN BJT. (A PNP BJT would have a P+ emitter, N-type base, and P-type collector.) NPN transistors exhibit higher transconductance and ... As explained in the PN diode analysis, the minority-carrier current is dominated by the diffusion current. The sign of I C is defined in Fig. 8–2a and is positive.
