    • The present invention describes a skew compensation circuit that can compensate for changes in signal skew in response to changes in external environments and processes. The skew compensation circuit includes a controller for outputting a control signal according to whether an external power supply is supplied and its operation mode. The skew compensation circuit also includes a signal output unit which selects either a normal path or a skew reduction path according to the control signal and outputs an input signal through the selected path.
    • 本发明描述了一种可以补偿响应于外部环境和过程变化的信号偏差变化的偏斜补偿电路。 偏斜补偿电路包括:控制器,用于根据外部电源是否提供控制信号及其运行模式来输出。 偏斜补偿电路还包括根据控制信号选择正常路径或偏斜减少路径的信号输出单元,并通过所选路径输出输入信号。
