Q. Explain The Input Characteristics Of Common Emitter Configuration?Input characteristics:In the figure the abscissa is the base current IB, The ordinate is the base to emitter voltage VBE, and the curves are given for various values of collector to emitter voltage VCE. We observe that, with the collector shorted to the emitter and the emitter forward biased, the input characteristics is essentially that of a forward biased diode. If VBE becomes 0,then IB will be 0,since under these conditions both emitter and collector junctions will be short circuited. In general increasing VCE with constant VBE causes a decrease in base width WB' and results in a decreasing recombination base current. These considerations account for the input characteristics.
