    • A P-domino register has a domino stage, a write stage, an inverter, a high keeper path, a low keeper path, and an output stage. The domino stage evaluates a logic function based on at least one input data signal and a pulsed clock signal. The pulsed clock signal lags a symmetric clock signal. The domino stage pre-discharges a pre-discharged node low when the symmetric clock signal is high and opens an evaluation window when the pulsed clock signal goes low, and pulls the pre-discharged node high if it evaluates, and keeps the pre-discharged node low if it fails to evaluate. The output stage provides an output signal based on states of the pre-discharged node and a second preliminary output node.
    • 多米诺骨牌登记册具有多米诺骨牌阶段,写阶段,逆变器,高守护者路径,低守护者路径和输出阶段。 多米诺骨牌阶段基于至少一个输入数据信号和脉冲时钟信号来评估逻辑功能。 脉冲时钟信号滞后于对称时钟信号。 当对称时钟信号为高电平时,多米诺舞台预放电节点为低电平,当脉冲时钟信号变低时打开评估窗口,如果评估则将预放电节点拉高,并保持预放电 节点如果不能评估,则为低。 输出级基于预放电节点和第二初步输出节点的状态提供输出信号。
