The potential of a point is related to the reference point, and the voltage (the potential difference of two points is independent of the reference point), at a point where the voltage of the 2 point is determined, the potential of one spot is raised and the potential of the other point is raised automatically. This is like standing on the shoulders of giants is a truth.

The features of the bootstrap circuit are: input pulse signal, charge and discharge of the capacitor and the characteristics of the voltage can not be mutated, and the unidirectional anti-flow of the diode.

When the Pulse output L signal capacitance left negative right is charged to the right end of the voltage VCC; When the pulse output becomes H, the capacitance left end voltage changes from 0 to H=VCC, because the voltage at both ends of the capacitor can not be mutated (the original voltage at both ends is VCC), and the right potential is raised when the left potential is lifted. The voltage is lifted by charging the next capacitor through the diode.
