Abstract: The present disclosure relates to a semiconductor device package which includes a carrier, an electronic component disposed on the carrier, and a package body disposed on the carrier and encapsulating the electronic component. A shield is disposed on the package body. The shield includes multiple non-magnetic conductive layers, multiple insulating layers and multiple magnetic conductive layers. At least one of the insulating layers is located between each non-magnetic conductive layer and a neighboring magnetic conductive layer.

Abstract: The present disclosure relates to a semiconductor device package which includes a carrier, an electronic component, conductive elements, a package body, a shield, a magnetic insulating layer, and a patterned conductive layer. The carrier has a top surface on which the electronic component is disposed. The conductive elements are disposed on the top surface of the carrier. The package body is disposed on the top surface of the carrier and encapsulates the electronic component and a portion of each of the conductive elements. The shield is disposed on the package body and covers an exterior of the package body. The magnetic insulating layer is disposed on a top surface of the shield. The patterned conductive layer is disposed on the magnetic insulating layer. Each of the conductive elements electrically connects the patterned conductive layer to the electronic component.

Abstract: A switched capacitor circuit for use in a voltage controlled oscillator (VCO) capable of minimizing clock feedthrough effect and an undesired momentary frequency drift in the VCO output frequency when the switched capacitor circuit is shut off. By gradually switching the switched capacitor circuit from an on state to an off state the clock feedthrough effect can be minimized. Several differently sized switch elements are used to selectively switch the capacitor from an internal capacitive node to ground. When switching the switched capacitor circuit to an off state, the control signals are sequenced to shut the switch elements off in order based on decreasing switch size. The smallest switch element can have a low-pass filter added to its control terminal to further decrease the clock feedthrough effect.
