摘要： The present invention provides several scalable integrated circuit high density capacitors and their layout techniques. The capacitors are scaled, for example, by varying the number of metal layers and/or the area of the metal layers used to form the capacitors. The capacitors use different metallization patterns to form the metal layers, and different via patterns to couple adjacent metal layers. In embodiments, optional shields are included as the top-most and/or bottom-most layers of the capacitors, and/or as side shields, to reduce unwanted parasitic capacitance.

摘要： Power over Ethernet (PoE) communication systems provide power and data communications over the same communications link, where a power source device (PSE) provides DC power (for example, 48 volts DC) to a powered device (PD). The DC power is transmitted simultaneously over the same communications medium with the high speed data from one node to the other node. The PSE typically includes a controller that controls the DC power provided to the PD at the second node of the communications link. The PSE controller measures the voltage, current, and temperature of the outgoing and incoming DC supply lines to characterize the power requirements of the PD. The PSE controller includes a resistorless switch to measure the current. The resistorless switch includes a sense transistor and a current mirror to allowing the PSE controller to calculate the current based upon a replica current.

摘要： A system and method for providing a low power warning in a portable communication device based on predicted device utilization. Various aspects of the present invention may comprise monitoring power utilization for a portable communication device. A power utilization profile may be determined based, at least in part, on the results of the power utilization monitoring. Power availability for the portable communication device may be determined. Future power need for the portable communication device may be predicted based, at least in part, on the determined power utilization profile. The predicted future power need and the determined power availability may be analyzed to determine whether to generate a warning indicating a potential future power shortage. If it is determined that a potential future power shortage warning should be generated, such a warning may be generated.
