  • Patent number: 7554166
    Abstract: A component having an airdome enclosure that protects the component from its external environment. An airdome enclosure according to the present techniques avoids the high costs of employing special materials and/or specialized process steps in the manufacture of a component. An electronic component according to the present techniques includes a set of substructures formed on a substrate and an airdome enclosure over the substructures that protects the substructures and that hinders the formation of parasitic capacitances among the substructures.

  • Patent number: 7486143
    Abstract: An embodiment of a circuit for biasing a transistor such as an amplifier transistor includes reference and bias nodes, and includes buffer, reference, and feedback stages. The reference node receives a reference current, and the bias node, which is for coupling to the transistor, carries a bias signal. The buffer stage buffers the reference node from the bias node. The reference stage generates the bias signal from the reference current, and the bias signal causes the transistor to conduct a bias current that is proportional to the reference current. And the feedback stage is coupled between the reference and bias nodes. As compared to known bias circuits, such a bias circuit may reduce the amplitude and duration of a transient overshoot in the bias current of a field-effect transistor when the DC component of the transistor's drain voltage transitions from one value to another value.
