The chapter discusses the frequency response of common source (CS) and common emitter (CE) amplifiers, including their equivalent small signal models and how to derive their output characteristics. The interaction between C-R and R-C circuits is analyzed to determine cutoff frequencies and gain, emphasizing the relationships between pole locations in the transfer function and the frequency response in the s-domain. Additionally, the importance of coupling capacitors in amplifier design is highlighted, stressing the need for numerical examples and design guidelines in subsequent lessons.

The unified model of amplifiers can be constructed using C-R and R-C circuits to evaluate their frequency response.
The location of poles in transfer functions directly relates to cutoff frequencies in frequency responses.
Cutoff frequencies can be influenced by component values such as capacitors in the amplifier's input and output stages.
The output behavior of an amplifier circuit over a range of frequencies, characterized by its gain and phase characteristics.
A representation of an amplifier that combines the effects of passive components (resistors and capacitors) with the active components to predict behavior in frequency response analysis.
The frequency at which the output power of the amplifier is reduced to half of its maximum value, critical for determining the bandwidth of the amplifier.
