Abstract
An integrated circuit may include a reference voltage generating circuit for generating a reference voltage. The reference voltage generating circuit may include a digital operation circuit and a digital-to-analog converter. The digital operation circuit is configured to adjust a reference voltage to temperature code relationship using a coefficient that adjusts a relative relationship between the reference voltage and the temperature code, and separate code that adjusts an absolute relationship between the reference voltage and the temperature code, wherein the temperature code reflects a temperature at the integrated circuit. The digital-to-analog converter is configured to generate the reference voltage based on an output from the digital operation circuit.
