Temperature sensor and temperature measurement method

Abstract

The invention relates to the technical field of temperature measurement, and provides a temperature sensor and a temperature measurement method. The temperature sensor comprises an oscillator, a counter and a calculator. The oscillator is used for outputting periodic signals at a certain frequency to the counter, the counter is used for counting the periodic signals and sending a count value of the signals and total time duration of the signals to the calculator, and the calculator is used for calculating a temperature value according to the count value of the signals and the total time duration of the signals. Compared with the prior art, the quantization function of an analog-to-digital converter in the prior art is completed through the simple counter, and due to the fact that the counter is quite easy to implement, the complexity of the link of converting analog quantity to digital quantity in the prior art is simplified; the temperature sensor and the temperature measurement method have the advantages of being simple in structure, easy to implement, small in occupied chip area and low in power dissipation.

Description

technical field [0001] The invention relates to the technical field of temperature detection, in particular to a temperature sensor and a temperature detection method. Background technique [0002] With the development of electronic information technology and the improvement of people's living standards, people's requirements for chips are getting higher and higher: chips not only need to support more functions, but also need to have higher performance and lower cost. These increasingly stringent requirements pose more and more challenges to the design of the chip, and every module in the chip must strive for perfection. Unfortunately, as the feature size of the CMOS process becomes smaller and smaller, although the chip can be made faster and smaller, the impact of various non-ideal factors, such as process deviation and temperature characteristics, on the chip is also increasing. Big. The key modules in the chip must have the ability to resist these non-ideal factors in ...
