I would like to start a discussion on ideas about IoT sensors and mixed signal chips.

Thanks Diya,   Just to let you know, I'm a very experienced ASIC designer for many many years.  I posted a blog on the community called "Why is SoC Design so Hard?"  It touches a lot on IoT and basic architectures.   Here is a block diagram from the blog.
