Abstract:
1. A data sampler comprising: a first stage configured to receive differential signals and provide, based on the differential signals, a signal transition having a first edge rate in a first output signal and a signal transition having a second edge rate in a second output signal, wherein the first edge rate is different than the second edge rate; and a second stage configured to amplify the difference between the first output signal and the second output signal to provide regenerated output signals, wherein the second stage provides, based on the first edge rate and the second edge rate, a signal transition having a third edge rate in a first internal signal and a signal transition having a fourth edge rate in a second internal signal; wherein the first output signal and the second output signal are pre-charged to a first voltage during one state of a clock signal and the first internal signal and the second internal signal are pre-charged to a second voltage in response to the pre-charged first output signal and the pre-charged second output signal.
