2 stage opamps design?

Question

Accepted Answer

2 stage opamps design involves cascading two amplifier stages to achieve desired gain and bandwidth.

Two amplifier stages are connected in series to achieve higher gain and bandwidth.
The first stage provides most of the gain while the second stage provides additional gain and output drive capability.
Each stage can be designed using different amplifier configurations such as common-source, common-emitter, etc.
Careful consideration must be given to stability, phase margin, and frequency compensation in the design.
Examples of 2 stage opamps include Miller compensated opamps, telescopic cascode opamps, etc.
