In a circuit arrangement (1) it is provided for supplying an integrated circuit (4) with electrical energy in a reliable and low-emission manner that a first ground connection (14) of the integrated circuit (4) is connected to a circuit carrier ground (3) and that an external buffer capacitor (17) is connected to a supply connection (5) and a second ground connection (18) of the integrated circuit (4). The arrangement is further equipped with a supply unit (15), which has a current source behavior, at least at a clock frequency of the integrated circuit (4). The buffer capacitor (17) reduces load-related voltage fluctuations, the current source behavior of the supply unit (15) causing a decoupling of the frequency between the charging and discharging process of the buffer capacitor (17). The high-frequency discharging currents are tightly restricted in the circuit arrangement (1), thus preventing significant emission.
