Abstract: In an embodiment, a circuit includes a first branch coupled between a first node and a second node, the first branch including a first ceramic capacitor, the first ceramic capacitor including terminals configured to receive a first voltage applied therebetween. The circuit further includes a second branch coupled between the first node and a third node, the second branch including a second ceramic capacitor that is substantially identical to the first ceramic capacitor, the second ceramic capacitor including terminals configured to receive a second voltage applied therebetween. The circuit further includes a control circuit configured to modify the second voltage until a first current passing through the second node is substantially equal to a second current passing through the third node.

Abstract: An embodiment method for modifying the frequency of a clock signal clocking an integrated circuit supplied by a voltage controller comprises, in response to a command for the modification, varying the frequency of the clock signal at a rate allowing a supply voltage to be controlled by the controller. The variation comprises at least one series of successive divisions of the frequency of the clock signal into successive intermediate signals of respective intermediate frequencies.
