Learning ObjectivesAfter studying this module, the reader should have the ability to: Explain graphically the amplification process in a simple bipolar
amplifier circuit. Describe the small-signal hybrid-p equivalent circuit of a bipolar
transistor and to determine the values of the small-signal hybrid-p parameters.
Apply the small-signal hybrid-p equivalent circuit to various bipolar amplifier circuits to obtain the time-varying circuit characteristics.
Characterize the small-signal voltage and current gains and the input and output resistances of a common-emitter amplifier.
Characterize the small-signal voltage and current gains and the input and output resistances of an emitter-follower amplifier.
Characterize the small-signal voltage and current gains and the input and output resistances of a common-base amplifier.
Apply the bipolar small-signal equivalent circuit in the analysis of multistage amplifier circuits.
Common-emitter transistor characteristics, dc load line, and sinusoidal variation in base current, collector current, and collector-emitter voltage
Expanded small-signal model of the BJT, including the Early effect, for the case when the circuit contains the (a) transconductance and (b) the current gain parameters
A bipolar circuit with an emitter resistor, a voltage-divider biasing circuit, and a coupling capacitor
