摘要： A data sampler including a first stage and a second stage. The first stage is configured to receive differential signals and provide a first edge rate in a first output signal and a second edge rate in a second output signal based on the differential signals. The second stage is configured to amplify the difference between the first output signal and the second output signal to provide regenerated output signals. The second stage provides a third edge rate in a first internal signal and a fourth edge rate in a second internal signal based on the first edge rate and the second edge rate.
