    • A delay circuit has an input node receives an input pulsed signal. A buffer transfers the input signal to a floating node. A detector outputs to an output node an output voltage that has a first level, if the voltage at the floating node is below a threshold, and a second level otherwise. Two similar branches are used, one for controlling delays in the rising transitions and one for controlling delays in the falling transitions. For each branch, a reference terminal carries a reference voltage for biasing the floating node. A capacitor and a switch are coupled between the reference terminal and the floating node. The switch opens and closes responsive to the output voltage. When it opens, it shorts out the capacitor. An optional phase detector and delay code generator may be in a feedback arrangement, for continuously adjusting the reference voltages.
    • 延迟电路具有输入节点接收输入脉冲信号。 缓冲器将输入信号传送到浮动节点。 如果浮动节点处的电压低于阈值,则检测器向输出节点输出具有第一电平的输出电压,否则输出第二电平。 使用两个相似的分支,一个用于控制上升转换中的延迟,一个用于控制下降转换中的延迟。 对于每个分支,参考端子携带用于偏置浮动节点的参考电压。 电容器和开关耦合在参考端和浮动节点之间。 开关响应输出电压打开和关闭。 当它打开时,它会使电容器短路。 可选的相位检测器和延迟码发生器可以是反馈装置,用于连续地调节参考电压。
