Abstract
Provided are a temperature sensor for generating a sectional temperature code and sectional temperature detection method. In one embodiment, the temperature sensor includes a plurality of serially connected fixed delay cells inputting a temperature detection signal and delaying the temperature detection signal, a variable delay cell inputting the temperature detection signal and delaying the temperature detection signal; and a sectional discrimination logic unit latching outputs of the fixed delay cells in response to the variable delay cells and generating the sectional temperature code. The sectional discrimination logic unit discriminates the sectional temperatures based on temperatures where an output of the variable delay cell meets each of outputs of the fixed delay cells according to the change in the temperature, and generates temperature codes corresponding to the sectional temperatures.
