Abstract
Exemplary embodiments are directed to systems, devices, methods, and computer-readable media for reducing static and dynamic power consumption of a charge pump. In one embodiment, a device may include a plurality of switches, each switch of the plurality having a gate coupled to a dedicated driver of a plurality of drivers. The device may further include at least one clamp switch coupled to at least one driver of the plurality of drivers and configured to adjust a rail voltage of the at least one driver if an input voltage is greater than a threshold voltage. In another embodiment, the device may include a plurality of multiplexers, each multiplexer of the plurality of multiplexers coupled to a portion of an associated switch of the plurality of switches and configured to disable the portion of the associated switch if a clock frequency of the charge pump is below a threshold frequency.
