43. Limitation of CE and CS Amplifiers in Cascading - Part A
The chapter discusses the limitations of Common Emitter (CE) and Common Source (CS) amplifiers when cascading them. It explores how cascading can affect gain and frequency response, leading to a need for buffers to mitigate these effects. Key concepts include the computation of overall gain and upper cutoff frequency changes due to loading effects between cascaded stages.

Cascading CE and CS amplifiers can introduce attenuation in gain and changes in frequency response.
Buffers can help maintain desired characteristics by isolating stages and minimizing loading effects.
It is essential to consider both resistance and capacitance effects when analyzing cascaded amplifier configurations.
Common Emitter Amplifier
A type of amplifier configuration known for its high gain, commonly used in analog electronics.
Common Source Amplifier
A counterpart to the CE amplifier, used in MOSFET technologies, characterized by its ability to provide significant gain.
Cascading
The process of connecting multiple amplifier stages in series to achieve higher overall gain.
Buffer
An intermediary circuit that helps prevent loading effects when cascading amplifiers.
Loading Effect
The change in circuit behavior due to the current drawn by one stage affecting the operating point of another stage.
Upper Cutoff Frequency
The frequency at which the gain of an amplifier begins to severely attenuate, which can be affected by cascading effects.
