摘要： A methodology may be used that takes into account the inductive coupling of current transients on the power rails of a printed circuit board (PCB) that may be coupled to the barrel of a via. By taking into account the coupling of the current transients on the power rails of the PCB, more accurate and realistic modeling results may be obtained. Inductive coupling of the current transients from the power rails may be more pronounced at higher frequencies and may be additive for more layer transitions (e.g., more via transitions) of the PCB.

摘要： A digital signal waveform receiving circuit may be processed by a non-linear adaptive canonical correlation analysis circuit that may quantify and minimize crosstalk-induced jitter timing skew for improving set-up and hold timing margins of data streams on the receiving circuit. A non-linear adaptive canonical correlation analysis circuit may be placed between an incoming digital signal from a serial link and a PHY receiving layer of an information handling system 100. The PHY receiving layer of the information handling system may be coupled to the non-linear adaptive canonical correlation analysis circuit or may be coupled to the digital signal. This coupling selection may be automatically programmed depending on received signal cross-talk-induced jitter timing skew or may be programmed by a user of the information handling system.

摘要： A wavelet transform noise minimization circuit comprises a differential receiver, a voltage comparator, a wavelet transform circuit, an electrical idle (EI) detector circuit, a phase interpolator, a phase-locked-loop (PLL), and a reference clock buffer. The wavelet transform noise minimization circuit may be beneficially applied wherever there is non-deterministic (e.g., random) noise in the PHY layer during an electrical idle state. The wavelet transform noise minimization circuit may be used to improve noise margin during an electrical idle state, and/or reduce the occurrence of false activation of a PHY layer when in the electrical idle state.
