If you are subscribed by e-mail, you need not do anything; I apologize in advance for spamming you. This was the only way to inform people of the RSS feed change.
The old RSS feed used to be http://feeds.feedburner.com/circuitdesign/TSIB
and has been replaced with a new RSS feed: http://feeds.feedburner.com/CircuitDesign
I’ve been tweaking the site. I renamed it “Circuit Design” (as opposed to “Analog”) since it’s more about circuit design in general than analog circuits.
Please update your reader to reference the new feed.
