Abstract
A low power 1-tap decision feedback equalizer (DFE) is disclosed. The DFE can include a plurality of AC-coupling networks, each having an input coupled to an output of a continuous time linear equalizer (CTLE) within an active stage of a receiver to receive a corresponding pair of differential signals of data, and an output coupled to a respective one of a plurality of data samplers to present a high frequency component of the corresponding pair of differential signals to the respective data sampler. The DFE can further include a plurality of transport paths, each transport path coupled to a respective AC-coupling network to receive the corresponding pair of differential signals. Each transport path can include one of the data sampler and an injection element to passively inject an offset into the high frequency component at an input of the respective data sampler.
