Beschreibung
Zusammenfassung:	An apparatus includes a voltage regulator including a high-side field-effect transistor, a low-side field-effect transistor, an inductor, and a conductive net connecting the high-side field-effect transistor, the low-side field-effect transistor and the inductor. The apparatus further includes an attenuation circuit coupled to the conductive net, wherein the attenuation circuit includes an electronic switch that enables and disables an amount of attenuation provided by the attenuation circuit. Examples of the attenuation circuit include a snubber circuit and a boost resistor circuit.
