Designing LiDAR and more into Autonomous E racing
Steve Taranovich

I think that ROBORACE is one of the most intriguing Motorsports I have ever seen for advancing the technology necessary for safe and practical electric vehicles. Its uniqueness is in the fact that their race cars are driverless as well as being electric.
Extracting Loop Gain and Phase Information from Simulation
Michael Steffes  
8/9/2018   Post a comment
Modern high-speed op amps and Fully Differential Amplifiers (FDAs) push the limits in every direction to deliver the best harmonic distortion at the lowest quiescent power. This often leads to relatively low phase margin designs in what would normally appear to be benign application circuits.

Automotive Ignition systems
Scott Deuty  
7/27/2018   Post a comment
Automotive ignitions systems have seen many transitions over the years. Historically, the designs have matured from a magneto to today’s coil-over-spark plug designs. The progression follows the emergence of solid state electronics as well as the phasing out of mechanical components in favor of electrical components.

DC-DC Converters Redefined With 'Micro Modules'
Rudy Ramos  
7/5/2018   Post a comment
DC-DC converters operate at all power levels and complexities. At some low levels it can make sense to design and ‘make it yourself,’ but at higher powers, a pre-assembled module becomes more cost-effective. New ‘micromodules’ shift that point to lower levels.
