Abstract:
Embodiments include a pulsed decision feedback equalization (DFE) circuit. The DFE circuit may include a current integrating summer (CIS) circuit that passes one or more data signals on respective data nodes based on an input data signal and a clock signal. The DFE circuit may further include a correction circuit, such as a current digital-to-analog converter (IDAC) circuit, that may provide a correction circuit to a data node based on a prior bit of the input data signal. The correction circuit may provide a conductive path between a current source of the correction circuit and the data node for a time period that is less than the unit interval (UI) of the clock signal and/or data signal. The DFE circuit may include a plurality of correction circuits to provide respective correction signals based on different prior bits of the input data signal. Other embodiments may be described and claimed.
