Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the operating speed of sampling circuits is increased to meet higher data rates, then data transmission speed is improved, but data quality deteriorates due to signal integrity issues
Solution Approach 1:
The patent implements dynamic speed adjustment by detecting data patterns and controlling the operating speed of sampling circuits accordingly. The circuit operates at high speed for normal data transmission and reduces speed only when specific patterns are detected, making the speed adaptive rather than fixed. This resolves the contradiction by allowing high speed operation most of the time while temporarily reducing speed only when necessary for data quality.
Solution Approach 2:
The patent changes the operating speed parameter dynamically based on detected data patterns. By monitoring patterns in the data stream and adjusting the sampling clock speed accordingly, the system optimizes the balance between transmission speed and data quality. The speed parameter is modified only when pattern detection indicates potential quality issues, rather than maintaining a constant conservative speed.
2Reliability
If various operations are performed to improve data quality, then data transmission quality is improved, but device complexity increases
Solution Approach 1:
The patent extracts only the essential function needed for quality improvement - pattern detection and selective speed control - rather than implementing comprehensive signal processing operations. By isolating the specific operation (detecting certain data patterns and adjusting speed) from other potential operations, the circuit achieves quality improvement with minimal added complexity. Only the necessary speed control mechanism is added, not a full suite of signal processing functions.
Solution Approach 2:
The sampling circuit performs self-adjustment of its operating speed based on its own pattern detection capabilities. The circuit monitors its own data stream and autonomously controls its sampling clock speed without requiring external intervention or complex external control systems. This self-service approach improves data quality while avoiding the complexity of external control mechanisms.
3Reliability
If current consumption is increased to improve data quality, then data transmission quality is improved, but power consumption increases
Solution Approach 1:
The patent implements periodic speed reduction only when specific data patterns are detected, rather than continuously operating at high current consumption levels. The circuit alternates between high-speed operation (normal current consumption) and low-speed operation (reduced current consumption) based on pattern detection. This periodic action ensures data quality when needed while minimizing overall power consumption during normal operation.

AI summary
A data sampling circuit may include a pattern detection circuit configured to generate a slow signal by detecting a pattern of multibit data including input data, and a sampling circuit configured to sample the input data during an activation period of a sampling clock and having an operating speed of the sampling circuit reduced when the slow signal is activated.
