ABSTRACT:
The disclosure provides methods and apparatuses of measuring a temperature. A method of measuring a temperature can include generating a time varying signal that varies with time in a known manner, such as having a repeating sawtooth waveform. Further, the method can include generating a first intersecting signal that intersects with the time varying signal at a first time, and generating a second intersecting signal that varies with temperature and intersects with the time varying signal at a second time. Subsequently, the method can construct a pulse signal having a first edge corresponding to the first time and a second edge corresponding to the second time, with the pulse signal having a width corresponding to the temperature.
