This paper introduces a programmable frequency-voltage conversion circuit, the frequency signal is converted into a pulsed width signal that is proportional to the frequency signal by a CPLD, pulsed width signal controls analog switch to chop the wave reference voltage signal, the DC voltage signal is output after the chopped wave signal passing through low-pass filtering.
