Two methods used for judging feedback and calculating loop gain respectively in actual circuits are presented in the paper. These methods are intuitive and useful for analysis and design of electronic circuits in actuality. These two methods are proved using signal flow chart. The analysis and design of a buffer is presented as an example. The simulation results show that the phase margin of the buffer is 50 Deg after compensation.
