Sub-threshold voltage supply for IoT
- Thread starter Torq
- Start date
Just our of curiosity, why do you ask?
I am very curious about this power mode of operation so i am looking for new ASIC design opportunities in this field. I prefer to work on things which are interesting for me, this is my credo.
But i am not sure that anyone in the industry is close enough to represent sub-threshold chips to market. That is why i ask.

Intel demoed solar powered near-threshold Atoms a few years back if you remember.
Just looking around: Ambiq Micro – The low power revolution starts here -- but they are not a big company I guess.

Intel's experiments do not look like a serious try: they just lowered the supply voltage below normal, and that revealed inoperability of their RAM+Cache. It seems they didn't actually want to make a commercial product.
Anyway the near-threshold and the sub-threshold voltages are quite different from each other, because a power consumption may differ by a number of decades in both of this power modes. So, the sub-threshold mode is much more suitable for IoT and energy harvesting applications than near-threshold voltage supply.
But, thank You anyway. I never heard about Ambiq Micro.
