Abstract
A decision feedback equalizer (DFE) and method including a branch coupled to an input and including a sample-and-hold element configured to receive and sample a received input signal from the input and a current-integrating summer. The current-integrating summer is coupled to an output of the sample-and-hold element. The summer is configured to receive and sum currents representing at least one previous decision and an input sample. The at least one previous decision and the input sample are integrated onto a node, wherein the input sample is held constant during an integration period, thereby mitigating the effects of input transitions on an output of the summer.
