In a PNP transistor, due to doping the emitter conductivity is 10 times base conductivity. Electron diffusion length in a more heavily doped emitter is half the hole diffusion length in the base. The base width is one-tenth of the hole diffusion length in the base. The a and b of the transistor are _____ and ______.
1
a = 0.976, b = 40.7
2
a = 0.976, b = 2
3
a = 1.025, b = 4.1
4
a = 1.025, b = 40.7
