摘要： The present invention pertains to a voltage reference circuit based on temperature compensation, comprising positive and negative temperature coefficient generating units, temperature compensation circuit, image circuit and voltage divider. In this circuit, Item T is compensated with Item T, and Item T ln(T) is compensated by Item T in (T), which features a well-targeted compensation performance. The circuit outputs a reference voltage with zero temperature coefficient, which is independent to T and T ln (T). The output voltage value could be defined by adjusting the ratio of resistance in voltage divider. The invention provides a voltage reference circuit featuring good compensation, zero temperature coefficient and adjustable output voltage. The invention has a better compensation than the conventional one and a fixed output voltage, and it totally eliminates the temperature coefficient. The invention has wide application in analog IC and digital/analog mixed IC.
