    摘要： A signal isolator comprises an isolation barrier, a transmitter, a differentiator, and a recovery circuit. The transmitter is coupled to a first side of the isolation barrier and is configured to receive and convert an information signal to a differential signal that encodes information in the information signal in a single transition edge. The differentiator is coupled to a second side that is isolated from the first side of the isolation harrier and differentiates the differential signal. The recovery circuit is coupled to the differentiator and operates to recover an output information signal based on the information in the single transition edge.

    摘要： An active clamp device electrically couples first and second nodes in respective first and second supply domains referenced to ground potentials that can be different. The active clamp device comprises first and second active devices controlled by signals respectively referenced to the first and second supply domains that create a short-circuit or low impedance connection between the first and second nodes in normal operation and drive impedance between the first and second nodes high in response to a transient event.

    摘要： A semiconductor device comprises an integrated circuit formed on a substrate with a signal interface and at least one isolator capacitor. The integrated circuit comprises a plurality of interleaved inter-metal dielectric layers and interlayer dielectrics formed on the substrate, a thick passivation layer formed on the plurality of the interleaved inter-metal dielectric layers and interlayer dielectrics, and a thick metal layer formed on the thick passivation layer. The thick passivation layer has a thickness selected to be greater than the isolation thickness whereby testing for defects is eliminated. The one or more isolator capacitors comprise the thick metal layer and a metal layer in the plurality of interleaved inter-metal dielectric layers and interlayer dielectrics separated by the thick passivation layer as an insulator.

    摘要： A power over Ethernet (PoE) system has a reclassification functionality. The illustrative PoE system comprises a powered device (PD) and a power sourcing equipment (PSE) communicatively coupled to the PD. A classification identification component coupled to the PD encodes a classification value. A classification identification component can typically be implemented as a classification resistor, although any other suitable component such as a capacitor, inductor, register, or other structure or method can otherwise be implemented. The PoE system can further comprise a reclassification register in a non-volatile memory that stores a value indicative of a new classification state and a new classification identifier and a power switch that powers the powered device to a classification voltage. A PD controller is coupled to the powered device that reads the value indicative of the new classification state and, if the new classification state is asserted, reads the new classification identifier and sets classification according to the new classification identifier. If the new classification state is not asserted, the PD controller sets classification according to the classification identification component.
