Abstract
A novel high-speed differential receiver is disclosed that provides a new method and apparatus receiving and amplifying a small differential voltage with a rail-to-rail common mode voltage. The receiver output signals are differential signals with low skew and high symmetry. This high-speed differential receiver is based on a common mode voltage normalization, which is based on a differential phase splitting methodology, before the resulting signal is recombined, normalized and amplified. The method involves using a differential signal splitting followed by a common mode voltage normalization stage, then a controlled gain transimpedance amplification, and then amplification using one or two rail to rail amplification stages that are symmetrical and balanced in nature.
