What is biasing
Base bias characteristics
Advantage:Circuit simplicity.
Disadvantage:Q-point shift with temp.
Applications:Switching circuits only.
Base Bias equation
Voltage-Divider Bias Characteristics
Advantages:The circuit Q-
point values are stable
against changes in hFE.
Disadvantages:Requires
more components than most
other biasing circuits.
Applications:Used primarily
to bias linear amplifier.
Voltage-Divider Bias equations
Base Input Resistance
Emitter-bias Characteristics
Advantage:The circuit Q-point
values are stable against changes in
hFE.
Disadvantage:Requires the use of
dual-polarity power supply.
Applications:Used primarily to bias
linear amplifiers.
Emitter-biAs
Collector-Feedback
Characteristics
Advantage:A simple circuit
with relatively stable Q-point.
Disadvantage:Relatively poor
ac characteristics.
Applications:Used primarily to
bias linear amplifiers.
Collector-Feedback
Emitter-Feedback
Characteris
Advantage:A simple circuit
with relatively stable Q-point.
Disadvantage:Requires more
components than collector-
feedback bias.
Applications:Used primarily to
bias linear amplifiers.
