Question:

a. For the common-emitter characteristics of Fig. 3.14, find the dc beta at an operating point of VCE = +8 V and lc = 2 mA.
b. Find the value of a corresponding to this operating point.
c. At VCE = +8 V, find the corresponding value of ICEO.
d. Calculate the approximate value of ICBO using the dc beta value obtained in part (a).
