Question 3 An n'pn Si BJT is shown in Figure Q3(a). The emitter is heavily doped with 1020 cm3 whereas the base and collector are lightly doped with 5x1018 and 3x1018, respectively. The lengths of emitter, base, and collector are 0.5um, 0.2um, and 0.5 um.. The dielectric constant of silicon is 11.8 and the intrinsic carrier concentration at 300 K is 1.5x1010 cm3. Assume that a 0.026 eV at 300 K. 0.99, e...
