PROBLEM TO BE SOLVED: To design a power supply without increasing time and cost. SOLUTION: The method and system for feedback circuit design are disclosed. The 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 circuit network to the feedback stage if the initial phase margin is less than a threshold phase margin. The design of the impedance circuit network is determined such that the initial phase margin is increased. COPYRIGHT: (C)2008,JPO&INPIT
