Zusammenfassung: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.
