Abstract: A low quiescent current amplifier and driver having multiple amplifiers (e.g. Class AB and B amplifiers) work in concert to independently amplify all or a portion of a signal into multiple amplified signals combined into a unified signal. Operation of a second amplifier is slaved to operation of a first amplifier. Each amplifier may have its own feedback loop providing the same gain transfer function to align transitions of the multiple amplified signals. Operation of the first amplifier may be detected using a replica of a signal, stage or transconductance in the first amplifier. At the same threshold, operation of the first and second amplifiers may be transitioned, e.g., the second amplifier may transition between providing increasing or decreasing current and providing zero current while the first amplifier may transition between providing constant current and providing increasing or decreasing current.

Abstract: Presented are circuits and methods for providing real-time short-circuit detection, capable of detecting a short-circuit prior to occurrence of an over-limit current event. Such a circuit can be used to provide real-time short-circuit detection for a switched-mode system for a switched-mode system having a pre-driver and a power stage, and includes a reference block for generating a reference voltage according to drive signals provided by the pre-driver, and a comparator, which may be a synchronized comparator. The comparator is configured to compare the reference voltage to a switching node voltage generated in a power stage of the switched-mode system, and to produce an output enabling detection of the short-circuit in the switched-mode system.

Abstract: Methods, systems, and media are provided for delivering clustered search results for recent and non-recent events by maintaining the identification (ID) numbers of the respective clustered documents beyond the “fresh” life span of the clustered documents. When clusters are formed according to similar content, an ID number and associated attributes are assigned to each of the clusters. This provides a mechanism to track and retrieve the respective clusters for subsequent delivery of search results. The respective ID numbers of the clusters are maintained, even after the documents are no longer considered “fresh.” These similar-content clusters are further subdivided according to publication date. This provides individual subdivided clusters for similar content events that occurred at different time spans, which are delivered along with individual non-clustered search results in a SERP.
