Abstract: A progammable power supply for providing a regulated DC output power is disclosed. The power supply provides the output power to any one of a plurality of electronic devices adapted for receiving the output power at an operational voltage or an operational current. The power supply receives a programming signal to maintain the output power at the operational voltage or operational current associated with a particular selected electronic device. Accordingly, by varying the programming signal, the power supply can be programmed to provide output power to any one of several electronic devices having differing input power requirements.

Abstract: A method of forming a magnetic body, alternative to a ferrite core, on a printed circuit board is provided. A printed circuit board is set in a mold and injection molding is conducted. The mold comprises a fixed plate, an intermediate plate and a movable plate. A cavity in the intermediate plate is filled with a melted material (i.e., mixture of resin and magnetic filler) supplied via a sprue and a runner. A cavity in the movable plate is also filled with the material supplied to the cavity in the intermediate plate through a hole in the printed circuit board. When a magnetic body for noise control is directly injection molded onto the printed circuit board in such a way, no gap appears between the magnetic body and the printed circuit board. As a result, the magnetic body functions well as desired.

Abstract: A circuit for removing noise from the power supply of a clock generator. Switching regulator noise from the voltage regulator section can affect a clock chip when it is carried through the power plane or ground plane. In order to remove this, a ferrite bead is placed along the voltage supply line. A bulk capacitor with low equivalent series resistance is connected from the output side of the ferrite bead to ground. By properly selecting the size of the bead and capacitor, the noise is reduced. The result is that the clock does not drift so that functional failures are reduced.

Abstract: The present invention is directed towards a multilayered circuit module and a method for constructing such a module, wherein the module has passive components such as capacitors, inductors, transformers distributed into a ceramic substrate. This module provides an optimally close packing density of these components without wasting large areas of unused substrate. The module of the present invention weaves capacitors, inductors, and transformers into the substrate without the use of printed circuit boards and eliminating discrete components. The substrate of the module becomes a functional component itself, rather than just a block receptacle for discrete components. The module of the present invention provides a very densely packed power supply with good heat conduction properties and which is also less costly to build than HDI modules.

Abstract: The invention is a transformer having one winding, for example the secondary, built as tracings in a first multilayer PC board. The primary windings are made as a separate second PC board. In an exemplary embodiment of the invention, the second PC board containing the primary windings is attached to the first PC board by attachment tabs built into the second PC board, and the tabs are soldered to receiving attachment pads of the first PC board. In another exemplary embodiment of the invention, the first PC board has various other components mounted thereon. For example, the secondary windings of a power transformer along with the power supply circuits are all built into a first single PC board. In another exemplary embodiment of the invention, the windings are etched as traces in copper layers of the PC boards as spirals. The spiral of one copper layer is connected to the spiral of a different copper layer by a via, or vias, formed through the insulating layer of the PC board. The vias are drilled, cleaned, and plated, with conducting material, for example copper. By using multiple layers, and by connecting spiral windings of each layer to the windings of the next layer by use of vias, any number of turns can be built into a primary winding, or into a secondary winding.

Abstract: Inductor topologies for filters used in broadband applications are described. In one implementation, an apparatus, such as an interface module includes a printed circuit board and a filter. The filter includes a generally circular high Quality factor (Q) value spiral planar inductor etched directly into the printed circuit board. The generally circular high Q value spiral planar inductor is configured to operate in a broadband application. Other implementations involve the use of decoupling structures with respect to the planar inductors as well as a design methodology for the filters.
