The phenomenon known as “Early Effect” in a bipolar transistor refers to a reduction of the effective base-width caused by(A) Electron - hole recombination at the base(B) The reverse biasing of the base-collector junction(C) The forward biasing of the emitter-base junction(D) The early removal of stored base charge during saturation-to-cut off switching. |

Answer» The correct answer B Explanation: The reverse biasing of the base-collector junction. In the case of discussion of Early Effect in a bipolar transistor, there happens a reduction because of the reverse biasing of the base-collector junction, and it leads to a reduction in the effective base width. This can be explained as reverse biasing of the base means the relationship of how there is a negative direction which denotes that emitter junction is reverse biased. This causes electron-hole pairs to be generated. And while the electrons flow to the collector it makes the holes not able to flow out of the base contact. |
