Introduction

Craig Andrews is an inventor associated with Austin, Texas, and RF Micro Devices, Inc. His patent work addresses power control circuitry for mobile terminals. The available information identifies 1 patent associated with him.

Latest Patents

The patent “Reconfigurable Power Control for a Mobile Terminal” describes circuitry that can operate either as a low-dropout (LDO) voltage regulator or as a switching DC–DC converter. The circuitry controls the variable supply voltage delivered to a mobile terminal’s power amplifier.

In LDO mode, an analog control system uses an adjustable power-control signal and feedback about the supply voltage to control the first output transistor. A digital control system disables the second output transistor. In DC–DC converter mode, the analog system’s output stage is disabled, while the digital system controls both transistors using binary signals based on the power-control signal and feedback.

Career Highlights

Andrews’s identified patent concerns a configurable approach to power-amplifier supply control. Supporting both LDO and switching-converter operation in one circuit provides alternative ways to regulate a mobile terminal’s supply voltage.

Collaborations

The provided information lists Jackie Johnson and David C. Dening as Andrews’s coworkers. It does not specify their roles in the patent or describe particular collaborations.

Conclusion

Craig Andrews’s identified invention focuses on reconfigurable power-control circuitry that supports two operating modes for managing a mobile terminal’s power-amplifier supply.
