What are the advantages of cascaded amplifier over single stage amplifier?

Cascaded amplifiers offer several advantages over single-stage amplifiers, primarily in terms of gain and bandwidth. By combining multiple amplifier stages, cascaded configurations can achieve higher overall gain while maintaining stability and linearity. Additionally, they can be designed to optimize frequency response across a broader bandwidth, allowing for improved performance in various applications. This approach also enables better impedance matching between stages, enhancing overall signal integrity.
