As the concentration of impurity donor atoms increases, the distance between donor atoms decreases. The splitting of the donor level is caused by the interaction of donor atoms with each other. The discrete donor energy level in an n-type emitter splits into a band of energies. This leads to _ effective bandgap energy, which then causes the transistor gain to ___.

A. increased; increase
B. decreased; increase
C. increased; decrease
D. decreased; decrease

The base width modulation effect, or the Early effect means that, a reduction in base width will cause the gradient in the minority carrier concentration to _, which in turn causes an/a _____ in the diffusion current.

A. increase; increase
B. decrease; decrease
C. increase; decrease
D. decrease; increase

B. in the center; near the emitter edges; the center
C. near the emitter edges; in the center; the center
D. near the emitter edges; in the center; the edges
