| description | A method includes generating a first, second and third voltage output from a temperature sensing element of an integrated circuit using a respective, corresponding first, second and third, switched current source, for sequentially switching a respective first, second and third excitation current through the temperature sensing element. The third switched current source generates the corresponding third voltage output as a reference voltage between the first voltage and the second voltage. An error corrected difference is calculated between the first voltage and the second voltage using the reference voltage. In the method, the second excitation current is proportional to the first excitation current by a value n, and the third excitation current is proportional to the first excitation current by the square root of n. |
