Abstract
Systems are provided for producing a low frequency filter pole. A first bond pad is coupled to a power source. A second bond pad is inductively connected to the first bond pad by a first bond wire. A capacitor is connected to the second bond pad. A third bond pad is inductively connected to the second bond pad by a second bond wire. The second bond wire, in conjunction with the capacitor, forms a low frequency filter pole to mitigate noise in a regulated signal provided at the third bond pad.
Claims27
An apparatus for producing a low frequency filter pole, comprising:
- a first electrically conductive pad coupled to receive power;
- a second electrically conductive pad;
- a first wire that inductively connects the first bond pad to the second pad;
- a first capacitor connected to the second pad;
- a third electrically conductive pad;
- and
- a second wire that inductively connects the second pad to the third pad, the second wire and the capacitor forming a low frequency filter pole to mitigate noise in a power signal provided at the third pad.
A regulated power supply system, comprising:
- an external capacitor electrically connected between a first node and electrical ground;
- a first bond wire, having an associated inductance, that electrically connects the first node with a second node;
- and
- a second bond wire, having an associated inductance, that electrically connects a third node with the first node to provide a substantially regulated voltage at the third node, the external capacitor and the second bond wire forming a low frequency pole that mitigates high frequency noise in the regulated voltage at the third node.
A regulated power supply system, comprising:
- means for providing a substantially regulated voltage across a capacitor that is coupled to a first bond pad;
- means for inductively connecting the first bond pad with a second bond pad so as to provide a low frequency filter pole based on a capacitance of the capacitor and an inductance of the means for inductively connecting.
