Abstract
The invention provides a bond wire arrangement comprising a signal bond wire (1) for operably connecting a first electronic device (6) to a second electronic device (8), and a control bond wire (2) being arranged alongside the signal bond wire at a distance so as to have a magnetic coupling with the signal bond wire (1), and having a first end (11) coupled to ground, and a second end (12) coupled to ground via a resistive element (14). The proposed solution allows the control of the Q factor (losses) of wire bond inductors during assembly phase, which will save time and reduce overall design cycle as compared to known methods.
