This article presents a method for power integrity analysis in FPGA systems by configuring the FPGA to function as a vector network analyzer (VNA) test instrument for its own power distribution network (PDN).
In our first electrical engineering class, we learn that the voltage across an inductor is L di/dt. We are ingrained with the idea that the voltage across an inductor is generated by the changing current through it. Not so, says Larry Smith, industry Power Integrity expert from Qualcomm and member of the SIJ EAB.
Measuring ripple, noise and transients on today’s low-voltage DC power rails challenges most oscilloscopes. Download the app note for more information.
Signal Integrity Journal, covering signal integrity, power integrity and EMC/EMI related topics, has published its first printed magazine issue. Signal Integrity Journal was launched in September 2016 as an online magazine, and is now celebrating its success with this 2018 print edition (which is also available as a digital e-book). The magazine issue is available in print, distributed at worldwide SI/PI/EMI events, and as a .pdf download online.
Samtec has expanded their line of edge card connectors with 0.80 mm and 1.00 mm pitch sockets designed for higher speed applications and optimal mating alignment. The 0.80 mm pitch socket (HSEC8-DP Series) is a differential pair version of Samtec’s popular Edge Rate® 0.80 mm pitch sockets.
This presentation proposes using a pulse echo for time domain reflectometry (TDR) rather the commonly used step function echo. The echoed pulse response of a single symbol is convolved with the modulation signal levels to produce an effective reflection coefficient metric at a specified bit error ratio (BER). Learn more.
