The gain-bandwidth conflict is one the most important limitations of high gain feedback amplifiers. In this tutorial paper we will discuss in a unified manner the most important approaches aimed to design amplifiers with a constant closed-loop bandwidth. Advantages and drawbacks are evidenced and new potential solutions are also formulated.
