摘要： A decision feedback equalizer includes a summer, a slicer, and a feedback circuit. The summer is configured to receive an input signal and a correction signal from the feedback circuit and generate a summer output signal. The slicer includes a first slicer and a second slicer, both are configured to receive the summer output signal as an input, and output a slicer output signal. The feedback circuit is configured to receive the slicer output signal, and based on the slicer output signal, generate the correction signal. The input signal is received at a first clock rate. The first slicer and the second slicer sample the input signal at a second clock rate, about half the first clock rate.
