FREQUENCY CONTROL CIRCUIT |
摘要 |
<p>A frequency regulating circuit for the current-consumption-dependent clock supply of a circuit configuration includes a current measuring device for measuring the instantaneous current consumption of the circuit configuration, a controllable clock supply circuit, which can be connected to a clock input of the circuit configuration, and a control device for driving the clock supply circuit based upon the measured current consumption, an increase in the current consumption of the circuit configuration effecting a reduction in the clock frequency at the output of the clock supply circuit. Such a circuit ensures that a maximum permissible current consumption is not exceeded, but, at the same time, makes possible a maximum power of the circuit by a maximum clock frequency.</p> |
