    Abstract: An apparatus includes a substrate. A first conductive layer is on the substrate. The first conductive layer includes a first set of conductive segments and a second set of conductive segments. A second conductive layer is over the first conductive layer opposite the substrate. The second metal layer includes a third set of conductive segments and a fourth set of conductive segments. A first set of vias is between the first set of conductive segments and the third set of conductive segments. The first set of conductive segments, the third set of conductive segments, and the first set of vias form a first transformer winding. A second set of vias is between the second set of conductive segments and the fourth set of conductive segments. The second set of conductive segments, the fourth set of conductive segments, and the second set of vias form a second transformer winding.

    Abstract: An apparatus includes a substrate and first through fourth conductive layers. The first conductive layer is on the substrate and includes a first electromagnetic interference (EMI) shield. The second conductive layer is over the first conductive layer opposite the substrate and includes a first winding of a transformer. The third conductive layer is over the second conductive layer opposite the first conductive layer and includes a second EMI shield. The fourth conductive layer is over the third conductive layer opposite the second conductive layer and includes a second winding of the transformer.

    Abstract: A circuit includes a high-side driver having a high-side slew control input, a high-side drive input and a high-side drive output. A low-side driver has a low-side slew control input, a low-side drive input and a low-side drive output. Drive control circuitry has a high-side drive control output, a low-side drive control output, and a slew control output. The high-side drive control output is coupled to the high-side drive input, the low-side drive control output is coupled to the low-side drive input. The slew control output is coupled to at least one of the high-side slew control input and the low-side slew control input, and the drive control circuitry is configured to provide a slew control signal at the slew control output. The high-side and/or low-side driver is configured to modulate a slew rate of a drive signal at a respective drive output thereof based on the slew control signal.

    Abstract: A modulation device may include a variable burst regulator and a current-driven clock generator. The modulation device may include a first output terminal configured to provide a modulated voltage for an operating frequency over a modulation period. The current-driven clock generator may include a second input terminal configured to receive a buffered version of the modulated voltage. The current-driven clock generator may include a second output terminal configured to provide a modulated current during the modulation period. The operating frequency may be proportional to the modulated current. The operating frequency may control the operating frequency over the modulation period.
