Abstract
Described are concepts, systems, circuits, devices, methods, and techniques directed toward power management and control. In particular, described are concepts, systems, circuits, methods, and techniques for utilizing a linear regulator and a switched capacitor converter to provide power management and control for supplying multiple configurable output voltages to a supply modulation.
Claims30
A system having a pair of input terminals configured to be connected to terminals of an energy source and having a pair of output terminals configured to be connected to a radio frequency (RF) amplifier, the system comprising:
- a linear regulator configured to draw power at the input terminals and to output a regulated voltage;
- a switched capacitor converter coupled to the output of the linear regulator;
- and
- a supply modulator coupled to the output of the switched capacitor converter.
