@Junko: Speaking of IoT trend, how much in-depth analog expertise is needed for that?
The IoT is just a mirror-reflection on the rest of the world. Parts of it can be designed with off-the-shelf modules, in which case you don't really care if they are analog or digital so long as you know how to plug them together -- the trick comes when you are designing something from the bottom up -- and that something needs analog expertise -- at which point everyone starts running around in ever-decreasing circles shouting "Don't Panic!"
Replay available now: A handful of emerging network technologies are competing to be the preferred wide-area connection for the Internet of Things. All claim lower costs and power use than cellular but none have wide deployment yet. Listen in as proponents of leading contenders make their case to be the metro or national IoT network of the future. Rick Merritt, EE Times Silicon Valley Bureau Chief, moderators this discussion.
