  • Patent number: 12100669
    Abstract: Multi-component modules (MCMs), including configurable electromagnetic interference (EMI) shield structures and related methods, are disclosed. An EMI shield enclosing an IC or another electrical component in an MCM can protect other components within the MCM from EMI generated by the enclosed component. The EMI shield also protects the enclosed component from the EMI generated by other electrical components. An EMI shield with sidewall structures, in which vertical conductors supported by a wall medium electrically couple a lid of the EMI shield to a ground layer in a substrate, provides configurable EMI protection in an MCM. The EMI shield may also be employed to increase heat dissipation. The sidewall structures of the EMI shield are disposed on one or more sides of an electrical component and are configurable to provide a desired level of EMI isolation.

  • Patent number: 12092666
    Abstract: A power stage, comprising of multiple power MOSFETs and control and monitoring circuits, is an important part of voltage regulators. The voltage regulator controller typically monitors the power stage output current to implement control and protection functions. Traditional power stages mostly adapt monolithic solutions, suffering from performance inefficiencies due to the LDMOS process, while co-packaged solutions with combined VDMOS and LDMOS processes suffer from potential large current monitoring errors due to different operating temperatures. The current invention proposes a current monitoring circuit with temperature compensation to cancel the temperature coefficient mismatch between the external power MOSFET and the current monitoring circuit.
