CIRCUIT AND METHOD FOR SENSING TEMPERATURE |
摘要 |
The present invention relates to a circuit and a method for sensing a temperature. In accordance with an embodiment of the present invention, a circuit for sensing a temperature including: a bipolar transistor unit connected to a current source to output an output voltage which is inversely proportional to temperature; a variable reference voltage unit for providing a variable reference voltage which varies according to setting; a first amplifying unit for receiving the output voltage of the bipolar transistor unit and the variable reference voltage and performing differential amplification to output the amplified voltage; and a second amplifying unit for variably amplifying a variation of the output voltage of the first amplifying unit using a feedback variable resistor is provided. Further, a method for sensing a temperature using the same is provided. |
