Abstract :
We consider the problem of optimally allocating local feedback to the stages of a multistage amplifier. The local feedback gains affect many performance indices in a complicated and nonlinear fashion, making optimization of the feedback gains a very challenging problem. We show that geometric programming provides a complete solution
