초록

In this work, a Voltage-to-Frequency Converter(VFC) in which the output frequency is proportional to the input voltage is proposed. To obtain the temperature stable characteristics of the VFC circuit is designed by BiCMOS technology. The output frequency range is 24KHz to 65KHz 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 $\pm$0.5% in the temperature range $-25^{\circ}C$ to 75$^{\circ}C$.
