Abstract:
An apparatus configured to apply equalization to an input data signal and detect data based on the equalized data signal. The apparatus includes a passive equalizer comprising a first signal path configured to generate a first signal based on an input signal, and a second signal path configured to generate a second signal by filtering the input signal. The apparatus further includes a sense amplifier having an input circuit configured to generate a third signal related to a combination of the first and second signals, and a data detection circuit configured to generate data based on the third signal. The data detection circuit may be configured as a strong-arm latch. The third signal may be a differential current signal including positive and negative current components. The strong-arm latch generating data based on whether the positive current component is greater than the negative current component.
