Shared Adaptation Unit for Multi-Receiver Signal Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In high-speed integrated circuits, the pulse response effect causes receivers to struggle in accurately determining digital signals from analog pulses due to interference from previously sent pulses, leading to inefficiencies and potential errors, and current architectures require significant chip space and power for dedicated adaptation units for each receiver.
Innovation Solution
A shared adaptation unit is implemented among multiple receivers, allowing for the sharing of compensation values and iterative adjustments, reducing the need for individual adaptation units and minimizing chip space and power consumption while maintaining accurate signal determination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a dedicated adaptation unit is provided for each receiver, then each receiver can independently adjust compensation values for accurate signal determination, but chip space and power consumption increase significantly
Solution Approach 1:
The patent implements a shared adaptation unit that serves multiple receivers simultaneously. This single adaptation unit maintains compensation values that can be utilized by any number of receivers connected to the same communications link, eliminating the need for separate adaptation units at each receiver. The shared unit performs iterative adjustments to compensation values based on error information from any receiver, and all receivers benefit from these adjusted values, thus achieving multi-functionality and reducing chip space while maintaining signal determination accuracy.
2Measurement precision
If a dedicated adaptation unit is provided for each receiver, then each receiver can independently adjust compensation values for accurate signal determination, but power consumption increases significantly
Solution Approach 1:
The shared adaptation unit consolidates the power-consuming adaptation functionality into a single unit that serves multiple receivers. Instead of having multiple independent adaptation units each consuming power, one shared unit performs the iterative compensation value adjustments and makes these values available to all receivers, thereby significantly reducing total power consumption while maintaining the ability to accurately determine signals.
3Adaptability or versatility
If multiple adaptation units are used, then each receiver has dedicated adaptation capability, but device complexity increases
Solution Approach 1:
The patent reduces system complexity by implementing a single shared adaptation unit that provides adaptation capabilities to multiple receivers. This shared unit maintains and adjusts compensation values that are universally applicable to all receivers on the same communications link, eliminating the need for multiple independent adaptation units and their associated complexity, while preserving full adaptability through the shared iterative adjustment process.

AI summary
An apparatus and method are provided to enable an adaptation unit to be shared among a plurality of receivers. The adaptation unit provides compensation values to each receiver to enable each receiver to compensate for the pulse response effect experienced by that receiver. By sharing an adaptation unit among a plurality of receivers rather than having a dedicated adaptation unit for each receiver, the chip space needed is significantly reduced since the number of adaptation units that need to be implemented is significantly reduced. In addition, the fewer number of adaptation units leads to less power consumption during operation. Overall, the sharing of the adaptation unit enables greater efficiency and improved scalability to be achieved.
