    摘要: An apparatus and a method for sensing temperature are provided. The apparatus includes a first oscillation circuit, a pulse width generator, and a comparison circuit. The first oscillation circuit is for generating a first signal having a first frequency which is related to a to-be-sensed temperature. The pulse width generator is for generating a pulse width signal, the pulse width signal having a pulse width related to the to-be-sensed temperature. The comparison circuit is for generating an output signal indicative of the value of the to-be-sensed temperature according to the first signal and the pulse width signal.
