I'm pretty sure the ADC in most, if not all, micrcontrollers are
charge redistribution types.

If it wouldn't be too much trouble, could you change

Bruce,
Thank you for your critical evaluation of the interpolator circuitry.
I have no doubt that further improvements to the design are possible
and hope to inspire other amateurs on the list to come up with an
improved interpolator design. The circuit

The attached circuit illustrates how to construct a simple high
linearity ramp TAC.
The circuit has been used in various guises for decades.
The latest incarnations use ultra high speed IC processes to integrate
all components on chip to minimise interconnection inductances and

Bruce,
Thank You for posting a proper TAC, I'll give your circuit a try so I
improve my education in interpolator design before sharing any further
work with this list.
