    • In a clock noise canceling circuit, a coupler extracts a signal from a clock signal. A filter selects a harmonic component of a preset frequency in the extraction signal from the coupler. A phase shifter phase inverts the harmonic component of the preset frequency from the filter. An AGC amplifier amplifies the phase-inverted harmonic component from the phase shifter. Also, a combiner combines the amplified component from the phase shifter with the clock signal to eliminate the harmonic component of the preset frequency from the clock signal. A power detector detects a power level of the harmonic component of the preset frequency in an output signal of the combiner. Additionally, a controller controls gain of the automatic gain control amplifier based on the power level of the harmonic component detected by the power detector, thereby canceling noises.
    • 在时钟噪声消除电路中,耦合器从时钟信号中提取信号。 滤波器在来自耦合器的提取信号中选择预设频率的谐波分量。 移相器相位从滤波器反转预设频率的谐波分量。 AGC放大器放大来自移相器的相位反相谐波分量。 此外,组合器将来自移相器的放大组件与时钟信号相结合,以从时钟信号中消除预设频率的谐波分量。 功率检测器在组合器的输出信号中检测预设频率的谐波分量的功率电平。 此外,控制器基于由功率检测器检测到的谐波分量的功率电平来控制自动增益控制放大器的增益,从而消除噪声。
