Prelab
For the prelab, the unknown parameters are calculated using the "approximate
method".
IC is calculated by the relation:
IC =



VRE = VBE
IC =


= 1.2 mA
Assuming β = 100 (reasonable average value for low power signal transistors)
Thus, IB =


=

= 12 µA
Generally, a separate Voltage bias supply is not chosen, the main supply voltage (VCC)
is used through the dropping resistor R1 and R2. Thus R1 and R2 can now be...
