FREQUENCY CONTROL CIRCUIT

摘要

The invention relates to a frequency control circuit for supplying clock-pulses, depending on the current consumption, to a circuit arrangement. Said frequency control circuit comprises a current measuring device (2) for measuring the instantaneous current consumption of the circuit arrangement (1), a controllable clock-pulse supply circuit (4) which can be connected to a clock-pulse input of the circuit arrangement (1), and a control device (3) for controlling the clock-pulse supply circuit (4) on the basis of the measured current consumption. An increase in the current consumption of the circuit arrangement causes a reduction in the clock-pulse frequency at the output (6) of the clock-pulse supply circuit (4). Said circuit ensures that a maximum acceptable current consumption is not exceeded, at the same time enabling maximum power of the circuit due to a maximum clock-pulse frequency.
