Temperature sensor device and methods thereof |
摘要 |
A device having a temperature sensor device is disclosed. The temperature sensor device includes a complementary to absolute temperature (CTAT) module and a reference module. Both the temperature sensor and the reference voltage module provide signals, that vary in a complementary relationship with the variation in temperature. While the signals can be voltages or currents, for purposes of discussion the signals are discussed in terms of voltages herein. The reference module provides a signal that has a relatively small variation with temperature as compared to the variation in a signal provided by the CTAT module. The signals are provided to a comparator, which provides a temperature control signal based on a comparison of the input signals.
