WebJun 27, 2024 · However, statistical analysis can only implement linear time invariant (LTI) algorithms, such as CTLE, but not non-LTI blocks, such as DFE. To overcome this drawback, Altera IBIS-AMI models implement an approximated DFE model, which is modeled as an LTI block, in statistical analysis. This improves simulation accuracy, … Webadaptive CTLE based on the slope detection and the half-rate DFE. Then, the circuit design of the key modules is introduced in Section 3. We give the circuit layout and post-simulation results in Section 4. Finally, we draw conclusions in Section 5. 2 Arcitecture The overall structure consists of an adaptive CTLE and a half-rate DFE, as shown in
