提出了一种通过随机化时钟信号来降低电源/地和衬底耦合噪声的方法。伪随机数生成算法用于产生伪随机时钟。引入概率调整技术来补偿速度损失，允许确定伪随机时钟的平均频率。所提出的方法实现了超过24 dB的噪声衰减在中心频率的成本ooff小于4%的速度降低。
A methodology is proposed to reduce power/ground and substrate coupling noise by randomizing the clock signal. A pseudo-random number generation algorithm is used to produce a pseudo-random clock. A probability adjustment technique is introduced to compensate for the speed loss, permitting the average frequency of the pseudo-random clock to be determined. The proposed method achieves more than 24 dB attenuation in noise at the center frequency at a cost ooff less than 4% reduction in speed.
