Shared High-Frequency Oscillator Control for Multi-Module Radios
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile phone systems require multiple oscillators for different communication modules, leading to circuit redundancies, increased costs, and significant power consumption, which can result in power shortages when all modules are operating in busy mode.
Innovation Solution
A high frequency oscillator generates a shared high frequency signal that is enabled by an enable signal when any module switches to busy mode and disabled when all modules are in idle mode, reducing power consumption by ceasing the generation of the high frequency signal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple oscillators are used for different communication modules, then each module can operate independently, but circuit redundancies increase and power consumption becomes significant
Solution Approach 1:
The patent merges multiple oscillators into a single shared oscillator that serves multiple communication modules (mobile module, Bluetooth module, WiFi module). The oscillator is enabled only when needed by any module, reducing total power consumption while maintaining operational independence through selective activation.
Solution Approach 2:
The oscillator operates dynamically by being enabled or disabled based on the operational state of connected modules. When any module switches to busy mode, the oscillator is enabled; when all modules are in idle mode, the oscillator is disabled, creating a dynamic power management system.
2Adaptability or versatility
If multiple oscillators are used for different communication modules, then each module has dedicated frequency sources, but circuit complexity and costs increase
Solution Approach 1:
The oscillator is designed as a universal component that can serve multiple different communication modules (mobile module, Bluetooth module, WiFi module) with different frequency requirements. This multi-functional approach eliminates the need for dedicated oscillators for each module, reducing circuit complexity and cost.
Solution Approach 2:
Multiple dedicated oscillators are merged into a single shared oscillator resource that is dynamically allocated to different modules based on their operational needs, reducing overall circuit complexity while maintaining the ability to support multiple frequency requirements.
3Use of energy by stationary object
If a shared oscillator is used for multiple modules, then power consumption is reduced, but the oscillator must be dynamically enabled and disabled based on module states
Solution Approach 1:
The system implements feedback control where the operational state of each communication module is monitored and fed back to the oscillator control logic. This feedback mechanism automatically enables or disables the oscillator based on real-time module states, managing control complexity through automated decision-making.
Solution Approach 2:
The oscillator control system operates autonomously by monitoring module states and automatically adjusting its enable/disable status without requiring manual intervention. The system self-manages the complexity of coordinating multiple modules' frequency requirements.

AI summary
An embodiment of a communication system is provided, in which a high frequency oscillator generates a first high frequency signal upon receipt of no disable signal. The first high frequency signal is commonly shared by at least two modules. Each module coupled to the high frequency oscillator operates in either busy or idle mode, wherein the module operates at the first high frequency signal when in busy mode, and asserts a request signal when in idle mode. A disablement unit, coupled to the first and second modules, asserts the disable signal to the high frequency oscillator when all of the request signals are asserted, thereby forcing the high frequency oscillator to cease the generation of the first high frequency signal.
