If the DC base-emitter junction voltage, Vbe, for an NPN BJT in the forward-active region is equal to 658 mV then what is the collector current flowing in this BJT, Ic, in milliamps? Assume that the saturation current for this BJT, Is, is equal to 40 fA. (Note that 1 fA = 1 femtoamp = 1 x 10^-15 A.) Neglect the effects of base-width modulation. Also assume that the thermal voltage is equal to Vt = kt/q = 26mV. Since Ic is very sensitive to small changes in Vbe, be sure to use Vbe to the nearest millivolt when calculating your answer!
