Abstract
The invention provides a frequency-voltage converter having a voltage source; a first capacitor, a second capacitor, a current generator and a sequencer receiving a recurrent signal; said first capacitor being charged to a value Vo after a time To, then discharged by a discharge current Jd proportional to the square of the instantaneous residual voltage in said first capacitor, during a time T-To; the residual charge which is present in the first capacitor after the time T being recopied at the beginning of each recurrence into said second capacitor.
