Abstract
A semiconductor device includes a first voltage generating circuit configured to output a first voltage based on temperature; an analog-to-digital converter configured to convert the first voltage into a temperature code; a code conversion logic configured to output an offset code and a level code of a temperature section which the temperature belongs among temperature sections based on the temperature code; an offset voltage generating circuit configured to output an offset voltage based on the offset code; a second voltage generating circuit configured to output a second voltage having a constant value within a temperature section based on the level code; and a temperature compensation voltage generating circuit configured to receive the first voltage, the second voltage, the offset voltage, and a feedback voltage and output a temperature compensation voltage, the feedback voltage based on the first voltage, the second voltage, and the offset voltage.
