  • Patent number: 10073484
    Abstract: A Schmitt trigger circuit having an input coupled to a current summing junction. A trickle current source generates a trickle current applied to the current summing junction. A bandgap current source generates a bandgap current applied to the current summing junction (wherein the bandgap current is fixed when a supply voltage exceeds a threshold). A variable current source generates a variable current applied to the current summing junction (wherein the variable current varies dependent on the supply voltage). At the current summing junction, the variable current is offset against the trickle and bandgap currents with respect to generating a voltage that is sensed at the Schmitt trigger circuit input.

  • Patent number: 9946282
    Abstract: A voltage regulator includes a feedback regulation loop and a drive transistor configured to source current to a regulated output. A transient recovery circuit is coupled to the voltage regulator circuit and includes a first transistor coupled to source current into a control terminal of the drive transistor, wherein the source current is in addition to current sourced in response to operation of the feedback regulation loop. The first transistor is selectively actuated in response to a drop in voltage at the regulated output. The transient recovery circuit further includes a second transistor coupled to sink current from the regulated output. The sink current has a first non-zero magnitude in the quiescent operating mode of the regulator circuit. In response to an increase in voltage at the regulated output, the operation of the second transistor is modified to increase the sink current to a second, greater, non-zero magnitude.

  • Publication number: 20180074838
    Abstract: Placement of virtual machines on physical hosts are based on differing initial policies and optimization policies set by a system administrator to more efficiently utilize system resources and serve the needs of different workloads. A scheduler mechanism allows a system administrator to select different initial placement policies for one or more host groups of physical hosts. The scheduler mechanism utilizes an optimizer that monitors host performance and adjusts the placement of virtual machines according to another set of optimization policies similarly selected by the system administrator for each of the host groups.
