Temperature sensor and method

A temperature sensor and a method for sensing temperature. The temperature sensor has a current generator module that generates a voltage (VPTAT) that is proportional to absolute temperature at an output terminal and a voltage (VCTAT) that is complementary to absolute temperature at another output t...

Zusammenfassung:A temperature sensor and a method for sensing temperature. The temperature sensor has a current generator module that generates a voltage (VPTAT) that is proportional to absolute temperature at an output terminal and a voltage (VCTAT) that is complementary to absolute temperature at another output terminal. A buffer stage has an input terminal coupled for receiving the voltage that is complementary to absolute temperature. An output terminal of the buffer stage is coupled to an input terminal of an amplifier stage. The voltage that is proportional to absolute temperature is input to another input terminal of the amplifier stage. The amplifier stage generates an output voltage from the voltages that are proportional to absolute temperature and complementary to absolute temperature.
