Shared Oscillator Architecture for Multi-Module Wireless Power Saving
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 for multiple modules, and a low frequency oscillator provides a shared low frequency signal, with an enablement unit managing power usage by enabling oscillators only when necessary, and auto frequency control maintaining signal accuracy.

Engineering Contradiction Analysis
1Reliability
If multiple oscillators are used for different communication modules, then each module can operate independently with dedicated frequency sources, but circuit redundancies increase and power consumption becomes significant
Solution Approach 1:
The patent merges multiple oscillator functions into a single shared oscillator that serves multiple communication modules (mobile module, Bluetooth module, WiFi module). The oscillator can be dynamically enabled for different modules based on their operational needs, eliminating the need for separate dedicated oscillators for each module while maintaining independent operation capability.
Solution Approach 2:
The shared oscillator is designed to serve multiple functions across different communication modules. It can provide frequency signals to the mobile module, Bluetooth module, and WiFi module as needed, making a single component universal for multiple purposes and reducing overall system power consumption.
2Reliability
If multiple oscillators are used for different communication modules, then each module has dedicated frequency sources, but circuit redundancies and costs increase
Solution Approach 1:
The patent combines multiple oscillator circuits into one shared oscillator that can serve multiple communication modules. This merging eliminates redundant oscillator circuits while maintaining the ability to provide dedicated frequency sources to each module when needed, thereby reducing device complexity and cost.
Solution Approach 2:
The system dynamically allocates the shared oscillator to different modules based on their operational requirements. The oscillator can be enabled for specific modules (mobile, Bluetooth, WiFi) as needed, providing dynamic frequency source availability without requiring static dedicated oscillators for each module.
3Productivity
If oscillators are always enabled for all modules, then all modules can operate in busy mode simultaneously, but power shortage occurs quickly
Solution Approach 1:
The patent implements periodic or on-demand activation of the shared oscillator based on which module needs to operate. Instead of continuously powering all modules simultaneously, the oscillator is enabled periodically or as needed for each module's operational requirements, reducing overall power consumption while maintaining simultaneous operation capability when necessary.

AI summary
A communication system and an oscillation signal provision method based thereon are provided. In the communication system, a high frequency oscillator generates a first high frequency signal upon receipt of an enable signal. The first high frequency signal is commonly shared by a first module and a second module. The first module is coupled to the high frequency oscillator, operating in either busy or idle mode, wherein the first module operates at the first high frequency signal when in busy mode. The second module converts the first high frequency signal to a second high frequency signal and operates at the second high frequency signal when in busy mode.
