Abstract

An assembly for powering a first circuit, including at least one ferrite bead in series with a diode between a first terminal of application of a first voltage and a first terminal of said first circuit.

First claim

What is claimed is:

1. An assembly for powering a first circuit, comprising at least one ferrite bead in series with a diode between a first terminal of application of a first voltage and a first terminal of said first circuit, wherein the ferrite bead has a resonance frequency approximately corresponding to a frequency of current edges provided by the first circuit.

2. The assembly of claim 1 , wherein the ferrite bead ensures a filtering function at frequencies greater than 10 MHz, preferably greater than 100 MHz.

3. The assembly of claim 1 , wherein at least one capacitor couples said first terminal of the first circuit to a second terminal of the first circuit.

4. The assembly of claim 1 , wherein the first voltage is delivered by a voltage source.

5. The assembly of claim 1 , forming a bootstrap assembly.

6. The assembly of claim 1 , further comprising a resistor in series with the ferrite bead and the diode.
