Hi,
has someone ever build the Ultra-Linear V→F Converter from AN14? What about noise, real world numbers and graphs on linearity and real world resolution?
While all of the analog gurus passed away will we stuck on further improvements?
I wonder if someone has thought about a voltage to frequency difference converter, based on a frequency reference such as OCXO or GPSDO. I think about "something" with voltage input and two frequency outputs. When input voltage is zero both outputs deliver the same frequency, if a voltage is applied to the input one outputs increases frequency, while the other decreases frequency. This difference can be measured with a time interval counter. Since they are available with 10 or 12 digits high resolution can be obtained. What do you think?
