Abstract
A method and system for feedback circuit design are disclosed. In one aspect, a method of feedback circuit design includes simulating a reference circuit design having a feedback stage at a target crossover frequency, determining an initial phase margin at the target crossover frequency, and adding an impedance network to the feedback stage if the initial phase margin is less than a threshold phase margin. The design of the impedance network is determined such that the initial phase margin is increased.
