摘要

在高速链路发射机中，产生抖动的一个主要原因是发射机的数据相关切换。这种开关导致电源R-L-C网络中的振荡。本文提出了一种面积有效的方法，通过将开关移到供电网络的谐振频率之外，而不考虑数据模式，从而降低供电噪声。该方案在65nm技术的HDMI发射机上实现。

Self-Induced Supply Noise Reduction Technique in GBPS Rate Transmitters

In high speed link transmitters, one major contributor of jitter is the data-dependant switching of the transmitters. Such switching leads to oscillations in the supply R-L-C network. This paper presents an area-efficient way to reduce this supply noise by shifting the switching beyond the resonance frequency of the supply network, irrespective of the data-pattern. This scheme is implemented in HDMI transmitter in 65nm technology.
