A voltage-frequency converter having an integrator of which the inverted input terminal is supplied a voltage to be converted while its non-inverted input terminal is supplied said voltage through a first switch means and a voltage comparator of which the inverted input terminal is supplied an output voltage of said integrator while its non-inverted input terminal is continuously supplied with a constant voltage and selectively supplied with said voltage to be converted through a second switch means, wherein an output of said voltage comparator is made to control said first and second switch means, whereby said voltage to be converted is converted into a signal having a frequency proportional to said voltage to be converted.
