QUESTION 5
What equal and opposite voltage can be applied to the EB and CB junctions (assume VEB=-
VCB > 3*VT) to make the slope of the minority carrier concentration exactly 4.4x1010/cm^4?
Assume this is a PNP silicon transistor at 300K, the silicon emitter is doped as 8.5*10%
18
/cc,
the base is doped as 7*1010lcc, and the collector is doped as 1.8*1015/cc, The metallurgical
width of the base is 1.04 microns, and ignore narrowing of the base by depletion widths,
and assume the minority carrier distribution is linear in the base. Use three significant digits
and fixed point notation.
