Abstract: Embodiments of the present disclosure provide a device and a method for monitoring power supply voltage of an electronic circuit. The device comprising: a voltage regulator configured to process the power supply voltage to generate a predetermined voltage; a critical timing generation module powered by the predetermined voltage and configured to generate a critical timing signal based on an original clock signal and a delay control signal, the critical timing signal being alternately in a first level state and a second level state; a control signal adjustment module configured to adjust the delay control signal based on the critical timing signal, wherein in a case that the critical timing signal is in the first level state, the delay control signal is increased, and in a case that the critical timing signal is in the second level state, the delay control signal is decreased; and a power supply drop sensing module powered by the power supply voltage and configured to generate a drop indication signal based on the original clock signal and the delay control signal, the drop indication signal indicating whether the power supply voltage drops below the predetermined voltage.

Abstract: A voltage detection circuit and method for an integrated circuit, and an integrated circuit are provided. The voltage detection circuit includes: a first current source, a first branch and a second branch. A current outputted by the first current source is allocated to the first branch and the second branch. The first branch includes a first voltage control current component and a first load connected in series. The second branch includes a current signal detection component and a second load connected in series. A voltage signal to be detected is inputted to a control signal input terminal of the first voltage control current component. The current signal detection component is configured to output, in real time, a preset signal characterizing a second current flowing through the second branch, to determine change of the voltage signal to be detected based on the preset signal.
