Abstract: Disclosed are a temperature measurement circuit and method. The circuit includes a first temperature sensing circuit, a second temperature sensing circuit and a data processing unit. The first temperature sensing circuit is configured to generate a first measurement signal for characterizing a temperature based on an inputted first current signal, a magnitude of the first current signal being correlated to temperature. The second temperature sensing circuit is configured to generate a second measurement signal for characterizing the temperature based on an inputted second current signal, the second current signal being independent of temperature. The data processing unit is configured to determine a current temperature based on a first characteristic parameter corresponding to the first measurement signal and a second characteristic parameter corresponding to the second measurement signal.
