This spring, Molex and Samtec announced a collaboration on next-generation data center solutions. SIJ caught up with Brian Vicich of Samtec, Inc and Brent Hatfield of Molex to find out what that means for engineers.

SIJ talked with Dave Kohlmeier about industry trends, how to foster innovation, and what today’s EDA customers need most.

Picotest.com has released the PerfectPulse signal generator, designed to be a low cost, pocket-sized, fast edge signal generator and TDR in one package. Picotest reports that this type of high-speedTDR/TDT has never been available in this portable form, requiring only a USB power source, and at this price point.

Dialog Semiconductor plc, a provider of highly integrated power management, AC/DC power conversion, charging, and Bluetooth^® low energy technology, today unveiled the DA7280, a new Haptic Driver Integrated Circuit (IC).

Richardson RFPD, Inc. announced today the availability and full design support capabilities for a new evaluation board from GaN Systems Inc. and pSemi Corporation.

The key benefits of gallium nitride (GaN) are, amongst others, high power density, best-in-class efficiency and decreased system costs. Infineon Technologies AG is starting volume production for CoolGaN™ products by the end of 2018, the company announced during PCIM Europe.

For this project, we will use an Atmel 328 microcontroller demo board, prepared with firmware to control it explicitly for our purposes, and with coaxial cables connected between the I/O pins and the input to the active probes of the scope. This interconnect provides a high bandwidth transmission line path for the signals.

If the die's I/O power rails are shared by the core power rails, here's a way to get your core power-rail measurements anyway.

How do you achieve high bandwidth in your measurements while minimizing current load on your DUT? Given that your DUT is a power rail, you really don't want to draw too much current from it., or your measurement system will distort the rail. But these two measurement criteria are at loggerheads with each other. It's a quandary, and it has to do with the fundamental nature of signals on interconnects.
