摘要：The present invention pertains to a voltage reference circuit based ontemperature compensation, comprising positive and negative temperature coefficient

generating units, temperature compensation circuit, image circuit and voltage divider. Inthis circuit, Item T is compensated with Item T, and Item T ln(T) is compensated by Item Tin (T), which features a well-targeted compensation performance. The circuit outputs areference 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 involtage divider. The invention provides a voltage reference circuit featuring good

compensation, zero temperature coefficient and adjustable output voltage. The inventionhas a better compensation than the conventional one and a fixed output voltage, and ittotally eliminates the temperature coefficient. The invention has wide application inanalog IC and digital/analog mixed IC.
