Back to Basics: Wireless charging Design How-To 5/31/2012 6 comments The concept of wirelessly charging devices has been around for a while, but is now rapidly gaining interest to make it more flexible and useable. But what are the different techniques available, and what are the design challenges an engineer needs to deal with?
FPGA testing for DO-254 compliance Design How-To 5/22/2012 1 comment This article describes key challenges that can be encountered when verifying FPGA pin-level requirements during board-level testing under DO-254 guidelines.
Project e-smart, Pt. 2: Vehicle controls, modeling, and simulations Design How-To 5/8/2012 Post a comment Converting a Smart ForTwo into an EV includes planning and specifying requirements for the electric vehicle, electric components selection, and E/E-architecture and control software design as well, as implementation of hardware and software by students of the University of Stuttgart. This part describes the vehicle control system; measurements, modeling and simulation of the vehicle; and an outlook on future EV issues.
Key methods for controlling EMC Design How-To 5/7/2012 2 comments Hardware engineers should address electromagnetic compatibility during the pc board design phase, starting with a low-inductance ground system, to ensure a system free of EMC faults.
HGST, LSI, PMC-Sierra demo 12G SAS News & Analysis 5/1/2012 Post a comment The HGST division of Western Digital demonstrated a solid-state disk drive with a 12 Gbit/second Serial Attached SCSI interface working with chips from LSI and PMC-Sierra.
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
