A detection circuit and an integrated circuit. The detection circuit is used for detecting the drift or an open circuit of a first capacitor (C) on a filtered second power source terminal (), and the second power source terminal () is suitable for acquiring a power source voltage from an unfiltered first power source terminal () by means of a first resistor (R), and is suitable for being coupled to a reference electric potential terminal () by means of the first capacitor (C). The detection circuit comprises a second resistor (R) and a second capacitor (C) that are connected in series and coupled between the first power source terminal () and the reference electric potential terminal (), wherein the second resistor (R) and the second capacitor (C) have the same time constant as the first resistor (R) and the first capacitor (C).
