GaN technology is pretty hot in some academic circles (see presentations at CMOSET conference for example)...that fact that process has been in development since 1999 tells you it is an easy process to work with...Kris
I remember when GaAs (gallium arsenide) was a hot research topic in the 1980's, but it never got beyond niche markets because CMOS advancing way beyond expectations.
I almost have to laugh that 0.25um GaN is cutting-edge, and 25nm CMOS has been in volume production for more than a year now (flash memory). I say "almost" because 0.25um GaN can run a lot faster than 0.25um Si; I'm curious what kind of speeds will be attainable at smaller geometries.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
