  • Current Monitor for Security
    Publication number: 20220043909
    Abstract: An apparatus includes an interface for an electronic device and a baseboard management controller (BMC). The BMC includes circuitry configured to, through the interface, monitor current usage by the electronic device, determine a security status of the electronic device based upon the current usage, and take a corrective action based upon the security status.

  • DC-DC voltage converter with reduced output voltage ripple
    Patent number: 7157891
    Abstract: An integrated DC—DC converter circuit in which multiple switched circuits operate in parallel to drive the output electrode with multiple pulsed charging voltages such that the corresponding respective output ripple voltage components combine with destructive interference, thereby reducing the net output ripple voltage.

  • Power MOS arrays with non-uniform polygate length
    Patent number: 6838711
    Abstract: In a MOS array, current loss at distances further away from the drain and source contacts is compensated for by adjusting the length of the polygate. In an array with drain and source contacts near the middle of the structure, the length of the polygate tapers off along the width of the polygate towards both ends of the polygate.
