Figure 2 shows the gain curve for the control loop in a Bode plot. It yields two important pieces of information. The frequency at which the gain is equal to 1—that is, at 0 dB—can be read ...

Electrical engineers will recognize the Bode plot as a plot of the frequency response of a system. It displays the frequency on the x-axis and the phase (in degrees) or magnitude (in dB) on the y-a… ...

Read this article online. This article will describe how Bode plots can be leveraged as a tool to quickly assess if your power-supply design will meet the requirements for dynamic control behavior.
