Integrated PA and SMPS Control for Adaptive Power Supply Response
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication devices, there is limited ability for the switching mode power supply (SMPS) to be adjusted based on the operating conditions of the power amplifier (PA), as they are typically controlled independently by the modem/transceiver system.
Innovation Solution
A power amplification control system that includes an interface to receive a transceiver control signal, generating both power amplifier and power supply control signals, with the power supply control component able to adjust based on both the transceiver signal and a local control signal from the power amplifier control component, allowing for integrated control of the power supply and amplifier.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the power amplifier and power supply are controlled independently by the modem/transceiver system, then the control architecture is simple, but the power supply cannot be adjusted based on power amplifier operating conditions
Solution Approach 1:
The patent merges the power amplifier control component and power supply control component into a single integrated control system. The power amplifier control component generates both power amplifier control signals and power supply control signals, eliminating the need for independent control paths and enabling the power supply to be adjusted based on power amplifier operating conditions while maintaining control architecture simplicity.
2Adaptability or versatility
If the power supply control component receives only transceiver control signals, then the control path is straightforward, but advanced power supply adjustments cannot be made based on local amplifier conditions
Solution Approach 1:
The power amplifier control component serves as an intermediary between the transceiver control signals and the power supply control component. It receives transceiver control signals, processes them along with local power amplifier operating condition information, and generates appropriate power supply control signals, thereby enabling advanced power supply adjustments without directly complicating the transceiver control path.
Solution Approach 2:
The system implements feedback by having the power amplifier control component monitor local power amplifier operating conditions and use this information to generate power supply control signals. This feedback mechanism enables the power supply to be dynamically adjusted based on actual amplifier performance and operating conditions.
3Adaptability or versatility
If customizations are made in the transceiver system to enable power supply adjustments, then power management capability is enhanced, but the transceiver system becomes more complex
Solution Approach 1:
The patent extracts the power supply control functionality from the transceiver system and places it in a separate power supply control component that is controlled by the power amplifier control component. This extraction eliminates the need for customizations in the transceiver system while preserving enhanced power management capabilities, as the power supply can be adjusted based on power amplifier operating conditions without modifying the transceiver architecture.
