    • A frequency multiplier is disclosed. A plurality of voltage regulators each regulate levels of voltages at first and second common nodes in response to a corresponding one of input signals from a voltage-controlled delay line. An input buffer charges the first node or discharges the second node in response to a feedback signal. An output buffer regulates a level of a voltage at an output node and outputs a frequency-multiplied clock signal and the feedback signal corresponding to the voltage level of the output node. A discharge circuit discharges the first node before a rising edge of each of the input signals from the voltage-controlled delay line is inputted. A charge circuit charges the second node before the rising edge of each of the input signals from the voltage-controlled delay line is inputted.
    • 公开了一种倍频器。 多个电压调节器响应于来自电压控制延迟线的输入信号中的相应一个,调节第一和第二公共节点处的电压电平。 输入缓冲器对第一节点进行充电或响应于反馈信号对第二节点进行放电。 输出缓冲器调节输出节点处的电压电平,并输出倍频时钟信号和对应于输出节点电压电平的反馈信号。 在输入来自压控延迟线的每个输入信号的上升沿之前,放电电路对第一节点放电。 在输入来自压控延迟线的每个输入信号的上升沿之前,充电电路对第二节点充电。

    • Disclosed is a Fe-based bulk amorphous alloy composition which forms a bulk amorphous substance due to its excellent amorphous formability when it is cooled to a temperature lower than its glass transition temperature from the liquid state at a relatively low cooling rate of 1000 K/s or less, has high warm processability in a low temperature range owing to its supercooled liquid region of 20K or higher and has excellent fluidity in the liquid state and thereby good castability. The Fe-based multi-element bulk amorphous alloy composition is represented by a formula of FeαCβSiγBxPyMa, in which M is at least one element selected from Ti(titanium), Cr(chromium), Mo(molybdenum), Nb(niobium), Zr(Zirconium), Ta(tantalum), W(tungsten) and V(vanadium), α, β, γ, x, y, and a each represent atomic % of iron(Fe), Carbon(C), silicon(Si), boron(B), phosphorus(P) and the selected metal element, in which α is 100-(β+γ+x+y+a) atomic %, β is 6 atomic % or more and 13 atomic % or less, γ is 1 atomic % or more and 5 atomic % or less, x is 4.5 atomic % or more and 9.5 atomic % or less, y is 3 atomic % or more and 10 atomic % or less and a is 0.1 atomic % or more and 6 atomic % or less.
