measuring resistance with RC circuit
LTC1799 actually evaluates current and voltage at its input and simulates RC evaluation. I used it for converting voltage into frequency ( temperature stability wasn't crucial then ).- Caledin

Using Buck Converter to regulate from 120V to low DC
probably it matters that AC voltage sometimes jumps to I don't know what value, and with a transformer it looks not that bad.- Caledin

measuring resistance with RC circuit
...probably LTC1799 and similar chips have been overlooked here. They are so small, inexpensive, nice things. They convert resistance into frequency using their own precise capacitor inside and the wonder is that the resistor being measured is at constant voltage. The temperature accuracy is...- Caledin
