摘要:
Example driver circuits can utilize shared-charge recycling charge pump structures. In particular, an example shared-charge recycling process may be applied to a clock buffer and charge transfer cells of the charge pump in a driver circuit. An example recycling process may include recycling of shared charges between the capacitors/capacitances in the charge transfer cells. An example recycling process may use the charges in one or more capacitors to charge one or more other capacitors before the charges are wasted or otherwise discharged to ground. Such recycling may significantly reduce the power consumption of the charge pump while still providing a high output voltage level, according to an example embodiment of the invention.
