WebApr 14, 2015 · This brief presents an adaptive continuous-time linear equalizer (CTLE) and one-tap decision feedback equalizer (DFE) using the spectrum balancing (SB) method. The SB method is extended for not only CTLE but also DFE with the aid of gain characteristics of one-tap DFE. Thus, adaptation loops for each equalizer type are merged to a single … 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

Open the system by typing serdesDesigner(‘TDadapt.mat’). You will see a system with a basic TX, 100-ohm channel with a loss of 16dB at 5GHz, and an RX containing a CTLE followed by a DFECDR.
WebMar 22, 2012 · If the DLE CTLE is designed to equalize for 3 pre-cursor pulses and 5 post-cursor pulses about the main pulse, then the CLE CTLE will have N*9 taps. The output of the DLE CTLE will further be sampled at one point per data time interval for data detection. The DLE CTLE will only cancel ISI at the data detection sample points. 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, …
WebMay 14, 2024 · The first experiment was to test the effectiveness of LEQ (linear EQ which consists of TX FIR, RX CTLE and RX FFE) and DFE at various configurations. Because CTLE is usually pre-determined with limited tunability and TX FIR and FFE are mathematically equivalent, we adjusted FFE tap length while fixing the TX FIR setting …
