Unfortunately I think it is likely too temperature dependent to do that.
But it could be interesting to see.
A 1:47AM thought, could the body diode be used to measure the die temperature?
Then you'd have the built in temperature sensor for temperature compensation as well.
But back to DTC's. So far all of them that I have seen used a pile of switched capacitors.
Or were just ST8P switches with "bring your own capacitors".
