EDC 3(1)(English) BJT (English)(Boylestad) ||
This video explains the basics of BJT with reference to CB, CE, and CC Configurations. End chapter problems 15, 19, and 26 have been solved.
15. a. Given an adc of 0.998, determine I C if I E 4 mA.
b. Determine adc if I E 2.8 mA, I C 2.75 mA and ICBO 0.1 mA
19. a. For the common-emitter characteristics of Fig. 3.13 , find the dc beta at an operating point
of V CE 6 V and I C 2 mA.
b. Find the value of a corresponding to this operating point.
c. At V CE 6 V, find the corresponding value of I CEO .
d. Calculate the approximate value of I CBO using the dc beta value obtained in part (a).
An input voltage of 2 V rms (measured from base to ground) is applied to the circuit of Fig. 3.21 .
Assuming that the emitter voltage follows the base voltage exactly and that V be (rms) 0.1 V,
calculate the circuit voltage amplification (Av = Vo greater than Vi) and emitter current for R E 1 k.
