    • A clock system of an integrated circuit includes first and second transistors forming a switch that is used when switching the clock system between a resonant mode of operation and a non-resonant mode of operation. An inductor forms a resonant circuit with capacitance of the clock system in resonant mode. The switch receives a clock signal and supplies the clock signal to the inductor when the switch is closed and disconnects the inductor from the clock system when the switch is open. First and second high impedance voltage sources supply respective first and second voltages to the switch and a gate voltage of the first transistor transitions with the clock signal around the first voltage and a gate voltage of the second transistor transitions with the clock signal around the second voltage such that near constant overdrive voltages are maintained for the first and second transistors.
    • 集成电路的时钟系统包括形成开关的第一和第二晶体管,该开关用于在谐振工作模式和非谐振工作模式之间切换时钟系统。 电感器在谐振模式下形成具有时钟系统的电容的谐振电路。 当开关闭合时,开关接收时钟信号并将时钟信号提供给电感器,当开关断开时,断开电感与时钟系统的连接。 第一和第二高阻抗电压源向开关提供相应的第一和第二电压,并且第一晶体管的栅极电压以围绕第一电压的时钟信号转变,并且第二晶体管的栅极电压以围绕第二电压的时钟信号转变 使得对于第一和第二晶体管保持接近恒定的过驱动电压。

    • A sense-amplifier monotizer includes an amplifier circuit and a keeper circuit. The amplifier circuit outputs a predetermined logic state while a clock signal is in a first phase, and samples a data signal and outputs at least one of the data signal and a complementary logic state of the data signal while the clock signal is in a second phase. A subsequent change of the data signal does not affect an output of the amplifier circuit once the data signal is sampled while the clock signal is in the second phase. The keeper circuit keeps a logic state of the sampled data signal once the data signal is sampled while the clock signal is in the second phase. The amplifier circuit may receive multiple data signals, and output a data signal selected by the select signal and/or a complementary value while the clock signal is in the second phase.
    • 感测放大器单调器包括放大器电路和保持器电路。 当时钟信号处于第一阶段时,放大器电路输出预定的逻辑状态,并对数据信号进行采样,并且在时钟信号处于第二阶段时输出数据信号和互补逻辑状态中的至少一个数据信号 。 一旦数据信号在时钟信号处于第二阶段被采样时,数据信号的随后变化就不影响放大器电路的输出。 一旦在时钟信号处于第二阶段,数据信号被采样,保持器电路将保持采样数据信号的逻辑状态。 放大器电路可以接收多个数据信号,并且在时钟信号处于第二阶段时输出由选择信号选择的数据信号和/或互补值。
