Question
7. Bipolar Junction Transistor (BJT) is a solid-state
current-controlled device which can be used to
electronically switch a circuit. You can think of it as
your normal fan or light switch, but instead of you
turning it on manually it can be controlled
electronically.
a)
Explain why an ordinary junction transistor
is called bipolar?
b)
Explain why silicon type transistors are
more often used than germanium type?
Given a transistor with B =100, determine
c)
the region of operation if:
i.
IB= 50µA and /c= 3mA
IB= 50µA and VCE= 5V
VBE= -2V and VCE= -1V
ii.
ii.
