Multiplexer With Embedded Equalizer Reducing Jitter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing signal transmission systems face challenges in reducing jitter caused by inter-symbol interference, which increases power consumption when attempting to mitigate this issue through the use of multiple multiplexers.
Innovation Solution
Incorporating an equalizer within the multiplexer to equalize signals passed through multiple paths, reducing inter-symbol interference and thereby minimizing jitter while also reducing the number of pre-driver stages and power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the number of multiplexers is increased to reduce jitter, then jitter is reduced, but power consumption increases
Solution Approach 1:
The patent merges the equalization function with the multiplexer by integrating an equalizer circuit directly into the multiplexer structure. This integration allows the multiplexer to perform both signal switching and equalization functions, reducing the need for separate pre-driver stages and thereby reducing overall power consumption while maintaining jitter reduction benefits
Solution Approach 2:
The multiplexer is designed with multi-functionality by incorporating the equalizer within its structure. The equalizer uses the same signal paths and switching mechanisms as the multiplexer itself, allowing a single component to serve multiple functions: signal selection, equalization, and driving capability, thus reducing the total component count and power consumption
2Reliability
If the number of multiplexers is increased to reduce inter-symbol interference, then inter-symbol interference is reduced, but device complexity increases
Solution Approach 1:
The equalizer is merged with the multiplexer circuitry, sharing the same signal paths, switching elements, and timing mechanisms. This integration eliminates the need for separate pre-driver stages and reduces the overall number of components required, thereby reducing device complexity while maintaining the ability to reduce inter-symbol interference
Solution Approach 2:
The multiplexer is designed to perform multiple functions including signal selection, equalization, and driving capabilities within a single integrated structure. The equalizer utilizes the same signal paths and switching mechanisms as the multiplexer itself, allowing one component to serve multiple purposes and reducing the total component count

AI summary
There is provided a method including receiving, by a multiplexer, input signals having a first rate, applying, by an equalizer in the multiplexer, equalization on the input signals passed through respective signal paths in the multiplexer, and outputting, by the multiplexer, an output signal comprising a selected signal of equalized versions of the input signals produced by the equalization, the output signal having a second rate greater than the first rate. There is further provided a device that includes a multiplexer and a signal driver having an input connected to the output of the equalizer. The multiplexer includes a plurality of inputs to receive respective input signals, an output to provide an output signal selected from among the input signals, and an equalizer to apply equalization on the input signals that are passed through the multiplexer, the equalization to provide the selected signals as equalized signals at the output of the multiplexer.
