Abstract: Low power decision feedback equalization (DFE) through applying DFE data to input data in a data latch is disclosed. In one embodiment, a decision feedback equalization (DFE) system to remove a post cursor intersymbol interference (ISI) through feeding back previous data scaled with adaptive weights to the DFE system, with each slice of the DFE system may include a first set of decision feedback digital to analog converters (DACs) to generate a first DFE data obtained through the feeding back the previous data scaled with the adaptive weights and a first data latch to generate an output data of the each slice through applying the first DFE data to an input data of the each slice in the first data latch to remove a first delay caused by performing the applying the first DFE data to the input data of the each slice outside of the first data latch.
