Patent ID: 8362824

Claim:
A charge pump, comprising: one or more uniform unit cells, the one or more uniform unit cells respectively comprising: two cross-coupled single-cell doubler circuits respectively comprising a flying capacitor, a set of power transistors coupled to the flying capacitor, and a dynamic inverter coupled to the flying capacitor and a power transistor of the set of power transistors, wherein, for a single-cell doubler circuit of the two cross-coupled single-cell doubler circuits, the dynamic inverter includes at least a first inverter transistor and a second inverter transistor that are directly coupled to a gate of the power transistor to facilitate control of a switching state of the power transistor based at least in part on an input voltage signal of the single-cell doubler circuit that is supplied to respective gates of the first inverter transistor and the second inverter transistor, wherein the two cross-coupled single-cell doubler circuits are configured to operate on respective input voltage signals, comprising the input voltage signal, according to respective clock signals to produce respective output voltage signals, and wherein the set of power transistors operate according to respective singular threshold voltages; and a loading circuit configured to operate on respective output voltages of the one or more uniform unit cells to generate an output voltage of the charge pump.
