An equalizer architecture based on asynchronous sampling is described. The circuit implementation is a hybrid feed-forward equalizer (FFE) using three digital postcursor taps realized via level-crossing samplers (LCSs) and inverter-based delays. Utilizing a current mode logic (CML)-based summer stage, an analog main …

A hybrid equalizer architecture based on asynchronous sampling for serial backplane links is described. The equalizer incorporates a continuous-time linear equalizer for the main tap and five digital post-cursor taps combined into a hybrid feed-forward equalizer (FFE) structure. Level-crossing samplers and inverter-based …
