A method of outputting temperature data in a semiconductor device and a temperature data output circuit are provided. A pulse signal is generated in response to a booting enable signal activated in response to a power-up signal and the generation is inactivated in response to a mode setting signal during a power-up operation. A comparison signal is generated in response to the pulse signal by comparing a reference voltage independent of temperature with a sense voltage that varies with temperature change. The temperature data is changed in response to the comparison signal. Thus, the temperature data output circuit can rapidly output the exact temperature of the semiconductor device measured during the power-up operation. |

A temperature invariant reference voltage and a temperature variant physical quantity, such as a voltage or current, are generated. The temperature variant physical quantity changes in response to a temperature of the integrated circuit. A temperature sensor circuit generates a voltage that is linearly dependent on the temperature. A level generator circuit generates 2n−1 voltage levels from the reference voltage. A comparator circuit, such as an analog-to-digital circuit, compares the voltage from the temperature sensor to the 2n−1 voltage levels to determine which level is closest. An n-bit digital output of the resulting level is proportional to the temperature of the integrated circuit. |

In an embodiment, one or more current sources and one or more switches are used to selectively provide a first amount of current (I1) and a second amount of current (I2) to the emitter of a transistor (Q1), during different time slots of a time period, to thereby produce a first base-emitter voltage (Vbe1) and a second base-emitter voltage (Vbe2), where I1=I2*M, and M is a known constant. An analog-to-digital converter (ADC) digitizes analog signals representative of the magnitudes Vbe1 and Vbe2. A difference is determined between the magnitudes of Vbe1 and Vbe2. A digital calculator produces a digital temperature reading (DTR) based on the difference between the magnitudes of Vbe1 and Vbe2. |
