摘要:
Methods and apparatus are provided for controlling at least one of a rise time and a fall time of a signal. A plurality of time shifted clock signals are generated; and a received data signal is sampled using a plurality of parallel data paths, where each of the data paths are controlled by a corresponding one of the plurality of time shifted clock signals. The plurality of time shifted clock signals can be generated, for example, by at least one delay element. The plurality of parallel data paths can be substantially identical and comprise, for example, at least one latch or at least one flip flop. Compensation can optionally be provided for variations in, for example, process corner, supply voltage, aging and operating temperature.
