Abstract

A circuit arrangement including a voltage supply device, which has an output, and that provides a variable supply voltage, a supply-voltage-controlled clock generator, which is coupled to the output of the voltage supply device, and that provides a system clock signal having a variable effective system clock frequency, a circuit section having a supply terminal, which is coupled to the output of the voltage supply device, and a clock input, which receives the system clock signal, and a regulating device that determines a supply-voltage-dependent supply current value and detects the extent to which the supply current value lies within a predetermined current value range, and which is coupled to the voltage supply device such that the supply voltage is regulated based on whether the supply current value lies within the predetermined current value range.
