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.
