a) Distinguish the major difference between a bipolar and a unipolar device. [2 Marks] b) Figure 2 shows the collector characteristics of a Bipolar Junction Transistor (BJT) configuration. Identify the ac beta (βac) and de beta (βcc) at Q-pt. Figure 2: A BJT collector characteristics [8 Marks] c) A certain BJT has a βas of 100 . When the base current is 50μA, identify the collector current.
d) Identify the dc current gain βdet and the emitter current IE for a transistor where IB=100μA and Ic=3.68 mA. [4 Marks]
For the BJT in Figure 3 , if the collector power dissipation is specified as 400 mW, identify the following: i. VCE at ICwax ii. IC at VCEmax iii. VCE at IC=1/2ICmax
