Choose a general purpose
transistor with a beta
gain higher than 100.
Decide on the collector
current.
The base bias voltage is
be 1/3 of the supply
voltage.
The current through the
base bias potential
divider is to be 1/10 of
the collector current.
Calculate the two base
resistor values, R1 and
R2.
The emitter voltage is
0.6 volts lower than the
base voltage.
The value of the emitter
resistor R4 is the
emitter voltage divided
by the collector
current.
The value of the
collector resistor R3 is
the supply voltage
divided by three times
the collector current.
The values of the
capacitors depend upon
the application. Study a
few circuits.
For common collector and
common base some of the
capacitors are connected
differently.
