Abstract
The digital temperature sensing circuit includes a temperature voltage generator configured to generate a temperature voltage varying with a temperature in response to a first reference voltage, divide a supply voltage in response to a second reference voltage, and generate a high voltage and a low voltage, a code voltage generator configured to divide the second reference voltage based on the high voltage and the low voltage and output divided voltages having different voltage levels, and a mode selector supplied with the temperature voltage and the divided voltages, and configured to output a first code or a second code in response to a mode select signal, wherein the first code and the second code have different numbers of bits.
