10312905 · 2019-06-04 · ·

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.

Managing a shoot-through condition in a component containing a push-pull output stage

Shoot-through condition in a component containing an amplifier with a push-pull output stage is managed. A first current in a first transistor of the output stage is mirrored to generate a first mirrored current. A second current in a second transistor of the output stage is mirrored to generate a second mirrored current. A sum of the first mirrored current and said second mirrored current is generated. When a magnitude of the sum exceeds a first pre-determined threshold, a respective control voltage of the first transistor and the second transistor is adjusted to reduce the first current and the second current at least until the sum falls below a second pre-determined threshold. In an embodiment, the first pre-determined threshold equals the second pre-determined threshold. In an embodiment, the component is a class-L power amplifier.

Nested microstrip systems and methods, and systems and methods encompassing same, are disclosed herein. In one example, a nested microstrip system includes a printed circuit board (PCB) having first and second layer levels, where first and second conductive traces are positioned at the second layer level. The first conductive trace is configured to include an orifice, and to extend between first and second locations along a first path, and the second conductive trace is positioned within the orifice. A non-conductive gap portion of the orifice exists between the first and second conductive traces so that the second conductive trace is electrically isolated from the first conductive trace. One or more first electromagnetic signals can be propagated along a first part of the first conductive trace, and one or more second electromagnetic signals can be propagated along at least a second part of the second conductive trace.
