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