Bipolar junction transistor
V-VBE=B*IB+D*IC
what does it mean B=? and D=?
SI=dIC/dICBO=(1+hfe)*B/(B+D*hfe)
IF B,D=0 SI=? AND B=D SI=?
SV=dIC/dVBE=(-hfe)/(B+D*hfe)
IF B,D=0 SV=? AND B=D SV=?
SH=dIC/dhfe=ICQ*B/(hfe*(B+D*hfe))
IF B,D=0 Sh=? B=D Sh=?
(1) The activation energy, Ea, is the energy difference between the reactants and the products in a chemical reaction.(2) The activation energy is the energy barrier that must be overcome by reactants for a reaction to occur.(3) The frequency factor, A, in the Arrhenius equation relates to the number of collisions and the fraction of those collisions that have the proper geometry for a reaction to occur.
