Abstract: Embodiments of the disclosure disclose a circuit and a method for temperature measurement. 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 representing temperature according to a first current signal input, and a magnitude of the first current signal is correlated to temperature. The second temperature sensing circuit is configured to generate a second measurement signal for representing temperature according to a second current signal input, and the second current signal is independent of temperature. The data processing unit is configured to determine a present temperature according to a first characteristic parameter corresponding to the first measurement signal and a second characteristic parameter corresponding to the second measurement signal. In this way, linearity of the circuit for temperature measurement when measuring the temperature can be improved, and accuracy of a temperature measurement result can be improved.

Abstract: Disclosed are an integrated circuit internal voltage detection circuit, a detection method, and an integrated circuit. The circuit comprises: a first current source, a first branch and a second branch, the first branch and the second branch being used for dividing a current signal output by the first current source. The first branch comprises a first voltage control current element and a first load connected in series, and the second branch comprises a current signal detection element and a second load connected in series. A control signal input end of the first voltage control current element inputs a voltage signal to be detected. The current signal detection element is used for outputting in real time a preset signal representing a second current flowing through the second branch, so that a change of the voltage signal to be detected is determined on the basis of the preset signal.
