What is Multistage Amplifier (or Cascade Amplifier)? Block Diagram, Working & Gain
The transistor circuit which involves more than one stage (or) multiple stages of amplification is called a multistage amplifier or cascaded amplifier. The block schematic of a multistage amplifier is shown in figure below. The overall gain of a multistage amplifier is the product of gain of individual stages.
