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

Another possible thing to try is one of the Miller integrator chips that
Tektronix used in their scopes and time base modules. I seem to remember that
at least one could yield 0.01% linearity. The 5Bxx and 7Bxx modules for the
5000 and 7000 series scopes are available in vast quantities, oft
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.

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
achieve sub

Merry Christmas from the far north to all the
Time-Nuts. As a gift for the holidays I have
created a free version of the PICTIC for you
and Didier has kindly posted the files at:

And to all a good night,
