The injected excess electron concentration profile in the base region of an npn BJT, biased in the active region, is linear, as shown in the figure. If the area of the emitter-base junction is 0.001 cm2, µn = 800 cm2/(V-s) in the base region and depletion layer widths are negligible, then the collector current Ic (in mA) at room temperature is __________. (Given: thermal voltage VT = 26 mV at room temperature, electronic charge q = $$1.6\times10^{-19}\;C$$ ) GATE ECE 2016 Set 3 Electronic Devices and VLSI - BJT and FET Question 9 English
