Abstract
A thermal sensor circuit that includes a temperature sensing circuit, an analog to digital converter, a processor and a divider circuit. The temperature sensing circuit generates a first temperature-dependent voltage and a second temperature-dependent voltage. The analog to digital converter converts a voltage difference between the first temperature-dependent voltage and the second temperature-dependent voltage to generate a first bit stream. The processor generates a second bit stream based on a thermal coefficient, wherein the thermal coefficient is used to calibrate the thermal sensor circuit. The processor further tunes the thermal coefficient until the output bit stream is equivalent to a bit stream of a reference model. The divider circuit divides the first bit stream by a denominator value to generate an output bit stream, wherein the denominator value is determined according to a bit value of the second bit stream.
