Abstract
Described are concepts, systems, circuits, devices, methods, and techniques directed toward power management and control. In particular, described are concepts, systems, circuits, devices, methods, and techniques for implementing hybrid supply generators and supply modulators that comprise a controllable linear regulator and a reconfigurable network of switches and capacitors to generate and supply a voltage level out of multiple available voltage levels.
Claims22
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 hybrid supply generator and supply modulator comprising
- a linear regulator configured to draw power at the input terminals, and
- a network of switches and at least one capacitor coupled to an output of the linear regulator;
- and
- a controller configured to control the hybrid supply generator and supply modulator to output a selected voltage level.
