Asynchronous Sampling-Based Hybrid Equalizer

Namik Kocaman, Michael M. Green

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 …
