Engineering Contradiction Analysis
1Speed
If the frequency of the clock is increased to enhance operating speed, then the operating speed is improved, but the valid section of signals is shortened
Solution Approach 1:
The patent implements dynamic timing adjustment by making the latching timing of the signal adaptable to different clock frequencies. The system dynamically adjusts when to latch the signal based on the actual clock frequency being used, allowing it to operate correctly across a wide range of frequencies from 100 MHz to 1 GHz while maintaining accurate signal reading despite varying valid sections.
2Speed
If the frequency of the clock is increased to enhance operating speed, then the operating speed is improved, but the accuracy of reading signals is deteriorated
Solution Approach 1:
The patent incorporates feedback mechanisms where the system monitors the clock frequency and adjusts its signal latching timing accordingly. This feedback loop ensures that even at higher clock frequencies where the valid section is shortened, the system can still accurately read signals by adapting its timing based on the actual operating conditions.
Solution Approach 2:
The latching timing is made dynamic rather than fixed, allowing the system to adapt to different clock frequencies. This dynamic adjustment maintains measurement precision across the full operating range by optimizing the latching moment for each specific frequency condition.
