摘要：
A charge pump driver circuit has a first charge switch that couples a first node of a flying capacitor to a first power supply node, and a second charge switch that couples a second node of the capacitor to a second power supply node. Control circuitry is coupled to open the second charge switch and discharge the second node of the capacitor, in response to a control signal. Other embodiments are also described and claimed.
