Continuous adaptive equalization at receiver is essential in high-speed serial link to compensate for channel and silicon characteristic changes due to environmental impact.
When CTLE is not part of continuous adaptation due to the complexity of least mean square (LMS) based method or inaccuracy of maximum eye-opening method, DFE only continuous adaptation is not sufficient to handle passive channel and silicon characteristic variations due to environmental impact for applications with large temperature span.
This paper presents a novel algorithm that utilizes DFE tap values to enable dynamic CTLE parameter adjustment based on the dynamic changes of operation conditions.
This study will introduce a novel algorithm that utilizes DFE tap values to enable dynamic CTLE parameter adjustment based on the dynamic changes of operation conditions.
