Innovation Solution
The integration of speed monitors and regulators within the integrated circuit, where speed detection results are used to generate control signals that adjust the regulated voltage, allowing for independent voltage control based on operational performance rather than voltage variations, ensuring consistent quality across different operational speeds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If voltage regulation is based on voltage variations, then the regulator can maintain voltage levels, but the quality consistency deteriorates due to manufacturing process variations and temperature effects
Solution Approach 1:
The patent implements feedback by monitoring the actual operational speed of the circuit and using this information to adjust the regulated voltage. The speed monitor continuously measures performance metrics and feeds this data back to the regulator, which then modifies the voltage output to maintain optimal performance. This closed-loop feedback system ensures quality consistency by adapting to manufacturing variations and environmental conditions in real-time.
Solution Approach 2:
The system performs self-service by autonomously monitoring its own performance through the speed monitor and automatically adjusting its voltage regulation without external intervention. The regulator uses the speed detection results to self-correct voltage levels, enabling the circuit to adapt to its actual operating conditions and maintain consistent quality across different manufacturing batches and temperature conditions.
2Adaptability or versatility
If a single global regulator is used for the entire integrated circuit, then the device complexity is reduced, but the adaptability to different circuit performance requirements deteriorates
Solution Approach 1:
The patent applies segmentation by dividing the integrated circuit into multiple functional blocks, each with its own dedicated regulator and speed monitor. This allows each segment to be independently controlled based on its specific performance requirements. The segmentation enables tailored voltage regulation for different circuit regions without requiring a complex centralized control system, as each segment operates autonomously with simple local feedback loops.
Solution Approach 2:
The system implements local quality by providing customized voltage regulation to each functional block based on its specific performance characteristics. Each regulator adjusts the voltage for its associated circuit block according to locally measured speed parameters, ensuring that each region receives the optimal voltage for its particular requirements rather than a uniform global voltage setting.
3Productivity
If regulated voltage is adjusted based on performance monitoring, then the operational efficiency is improved, but the device complexity increases due to additional monitoring circuits
Solution Approach 1:
The patent merges the speed monitoring function and voltage regulation function into an integrated system where the speed monitor and regulator work together as a unified control mechanism. By combining these functions and sharing common circuit elements and control logic, the system achieves performance-based voltage adjustment without proportionally increasing overall device complexity. The merged architecture allows efficient use of shared resources while maintaining the benefits of performance monitoring.
