High-voltage surge stoppers ensure reliability during power spikes Design How-To 3/29/2012 6 comments In automotive, industrial, and avionic applications, high-voltage power supply spikes are commonly encountered. The electronics within these systems must not only survive surges, but in many cases also operate reliably throughout the event—and devices charged via automobile power points (lighters) must also be protected.
FlexRay spec rev offers back compatibility, lower costs Design How-To 3/15/2012 Post a comment The FlexRay electrical physical layer spec Rev. 3.0.1 has been released and production of second generation transceivers has started. Semiconductor manufacturers have to ensure full device specific functional range in existing applications with a drop-in replacement.
We teardown a Chevy Volt (exclusive videos) Design How-To 3/12/2012 2 comments What makes a Chevy Volt tick (and whirr and hum) is revealed in these videos where the car was taken apart over three days—quality, ruggedness, and modularity for incorporating future technology are apparent.
Transmitter/receiver pair serves as antitheft alarm Design How-To 3/8/2012 3 comments Simple circuit consists of a transmitter/receiver pair that functions as an automobile antitheft alert system. When the vehicle leaves the area, this circuit sounds an alarm because the distance between the transmitter and receiver increases and the received power level falls below a predetermined threshold.
EIS simplifies battery measurement and characterization Design How-To 3/5/2012 3 comments Electrochemical impedance spectroscopy (EIS) is increasingly important for measuring and characterizing batteries and other electrochemical systems. This non-invasive measurement method can be exploited not only in modeling energy storage such as batteries and fuel cells, but also in basic battery research and diagnostics.
ISO 26262 cuts electronics complexity risks: Pt. 2- Design for robustness Design How-To 3/2/2012 Post a comment Future development and integration of automotive safety functions will strengthen the need to have safe system development processes and to provide evidence that all reasonable safety objectives are satisfied. ISO 26262 provides guidance to reduce these risks to a tolerable level by providing feasible requirements and processes.
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.
January 2016 Cartoon Caption ContestBob's punishment for missing his deadline was to be tied to his chair tantalizingly close to a disconnected cable, with one hand superglued to his desk and another to his chin, while the pages from his wall calendar were slowly torn away.122 comments
