Digital output temperature sensor and method of temperature sensing |
摘要 |
A temperature sensor generates a digital output signal representative of the absolute temperature of the sensor. The sensor includes a first circuit configured to generate a complementary to absolute temperature (CTAT) voltage signal and a second circuit configured to generate a proportional to absolute temperature (PTAT) current signal. A comparator receives the CTAT and PTAT signals and generates a comparison signal based on a comparison between the signals. A converter circuit receives the comparison signal and generates a digital output signal based on the comparison signal. The digital output signal is representative of the temperature of the sensor. |
