1. A semiconductor device, comprising:
a first voltage generating circuit configured to output a first voltage based on a 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 to which the temperature belongs among a plurality of 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 to which the temperature belongs among the plurality of temperature sections 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, the feedback voltage being based on the first voltage, the second voltage, and the offset voltage, and
output a temperature compensation voltage.
