This work presents methods for mitigating differential-to-common mode conversion noise in high-speed digital systems. As the modern high-speed digital signaling technologies demand faster data rate signals, electromagnetic interference (EMI) and electromagnetic compatibility (EMC) issues become more important than ever when designing high-speed digital systems. Also the density of printed circuit boards (PCBs) increases rapidly and integrated circuits are increasingly miniaturized, various trace discontinuities are inevitable in the design of high density PCBs. These trace discontinuities in PCBs make serious unwanted noise also known as differential-to-common mode conversion noise. The induced common mode noise can cause serious EMI issues, and degrade the signal integrity (SI) and power integrity (PI). In this thesis, various schemes are presented to suppress the differential-to-common mode conversion noise in various trace discontinuities in PCBs including right-angle bent differential lines, delay serpentine lines. Proposed methods for right-angle bent differential lines compensate the pahse differences between two differential lines and methods for delay serpentine lines equalize the even- and odd- mode velocities to mitigate mode conversion noise. Noise suppression characteristics are verified in both the frequency and time domains with S-parameters and eye diagram.
