发明名称 Waveform compensated output driver
摘要 An output driver that includes a waveform detector and a driver unit. The waveform detector receives at least one data signal, detects for particular patterns of interest (e.g., a sequence of zeros or ones) within the received data signal, and provides one or more control signals indicative of the detected patterns of interest. The driver unit receives the data signal and provides at least one output signal in response thereto. The driver unit further receives the control signal(s) and adjusts one or more characteristics of the output signal based on the received control signal(s). Various characteristics of the output signal (e.g., slew rate, delay, drive strength, and others) can be adjusted to achieved the desired result (e.g., reduced amount of skew, ISI). The driver unit can be designed to include a pre-driver that receives the data signal and provides at least one pre-drive signal and a driver that receives the pre-drive signal and provides the output signal. The pre-driver and drive can each further receive the control signal(s) and adjust one or more characteristics of its output signal based on the received control signal(s).
