In this work, a temperature stable voltage-to-frequency converter (VFC) in which the output frequency is proportional to the input voltage is proposed. The output frequency range is from 22 kHz to 60 kHz and the difference between simulated and calculated values is less than about 5% for this range of output frequency. The temperature variation of sample output frequencies is less than 0.5% in the temperature range -25C to 75C.
