However, a region of marginal stability exists where the system transient response oscillates and eventually damps out after a long settling time. In Figure 4, the gain-bandwidth is the crossover frequency, f cs. A major limiting factor of the maximum crossover frequency is the power supply switching frequency. Accord- ing to sampling theory, if the sampling frequency is less than 2 times the frequency of the informa- tion, the information will not be properly read. In a switched mode power supply, the switching frequency is seen in the output ripple, which is false information and must not be transmitted by the control loop.
