A more accurate voltage-to-time and then time-to-voltage conversion is accomplished by tailoring the amplitude versus time characteristics of the pulses generated in the voltage-to-time conversion. One embodiment includes applying a ramped voltage supply to an amplifier coupled between the voltage/time converter and the time/voltage converter. The ramped supply is arranged to condition the amplitude of a portion of respective pulses to include a slope similar to the ramped voltage applied to the time/voltage converter. This tends to effect a more accurate response in the time/voltage converter.
