The overall reason for cascading amplifiers is the need for an increase in amplifier output to meet a specific requirement, e.g., to increase the signal strength in a Television or radio receiver. Using a cascade, or multistage, amplifier can provide your design with a higher current gain or voltage gain.
What are the advantages of cascade amplifier?
- Enhanced performance and efficiency.
- Maximum flatness levels.
- Minimal noise figure in the range of 1-10GHz.
- Increased gain.
- Increased bandwidth allows the devices to be widely employed for high-voltage amplifier purposes.
- Hight input and output impedances.
What is a cascaded op-amp?
When op amp circuits are cascaded, each circuit in the string is called a stage; the original input signal is increased by the gain of the individual stage. Op amp circuits have the advantage that they can be cascaded without changing their input -output relationships.
