  • Publication number: 20220060503
    Abstract: Embodiments are directed to monitoring network traffic using NMCs that may be arranged to provide scores based on threat assessments associated with anomaly classes such that the anomaly classes may be associated with types of anomalous activity. NMCs may employ the anomaly classes, the scores, characteristics of the anomaly classes, or the like, to determine triage models. The NMCs may modify the scores based on the triage models or archival information associated with the anomaly classes. The NMCs may associate the modified scores with the anomaly classes. In response to detecting anomalous activity, the NMCs may provide other scores based on the anomalous activity and provide a report that includes the other scores to a user.

  • Patent number: 8089314
    Abstract: A slew rate improved operational amplifier circuit is provided to improve the slew rates of an operational amplifier with minimal sacrifices in power dissipation and other operational amplifier parameters. To improve the slew rates of operational amplifiers, additional current sources are activated when a slewing operation is detected. The detection of slewing operations and the activation of current sources upon detection can be implemented using two comparator circuits—one for a positive slewing operation, and one for a negative slewing operation. A sub-45 nm FinFET implementation of this slew rate improvement concept was implemented and compared against slew rate optimized individual two-stage operational amplifiers. Simulations show that slew rates were significantly improved by the implementation of the comparator circuits (5590 V/?s vs. 273 V/?s), with minimal increases in power dissipation (78 ?W vs. 46 ?W).
