摘要： A switching element is connected to an integrated circuit for shunting an ESD pulse away from the integrated circuit features. A plurality of detection circuits responsive to typical ESD waveform characteristics provide logical control of the switching means. In the preferred embodiment, a NAND gate drives the switching element. The first input to the NAND gate is a first RC network having a first time constant that exceeds the characteristic rise time of the typical ESD pulse, but not the characteristic duration of the typical ESD pulse. The second input to the NAND gate is a feedback loop from the NAND gate output. The feedback loop includes a second RC network having a second time constant that exceeds the duration of a noise pulse, a third RC network having a third time constant that approximates the characteristic duration of the typical ESD pulse, and an inverter between the second and third RC networks. Application of the ESD pulse causes the first input to drive the NAND gate, thus turning on the switching element, and if the ESD pulse is still present when the second time constant is exceeded, the switching means is latched on via the second input until the third time constant is exceeded.

摘要： A battery temperature monitoring circuit, which has a cold comparator and a hot comparator, achieves high accuracy in a small cell size by utilizing a cold current optimized for the cold comparator and a cold reference voltage, and a hot current optimized for the hot comparator and a hot reference voltage, along with switching circuitry that provides the cold current to the cold comparator as the battery temperature approaches the cold trip temperature, and the hot current to the hot comparator as the battery temperature approaches the hot trip temperature.

摘要： The line banding image artifact that results from the interaction of LCD ripple and LED flicker in an LCD device that utilizes LED backlighting strings is substantially reduced by selecting a number of LED strings, individually driving the number of LED strings with a corresponding number of identical clock signals that are equally phase delayed, and selecting the frequency of the clock signals so that the product of the frequency of the clock signal multiplied by the number of LED strings is equal to the line clock frequency.

摘要： Interface circuitry and method for transmitting and receiving downstream and upstream data signals simultaneously via a common conductor pair. The composite signal containing the downstream and upstream data signal components being conveyed by the common conductor pair is isolated, e.g., via signal filtering or buffering, and combined with an appropriately scaled inverse replica of the outgoing upstream data signal to subtract out upstream data signal components and thereby provide the downstream data signal substantially free of any upstream data signal components.

摘要： In semiconductor wafer manufacturing, processes such as analyzing test data associated with semiconductor wafers, interpreting the test data analysis, and acting on the test data interpretation and analysis are automated. Such automation can eliminate delays that were previously imposed by the action of test analysis engineers and wafer fabrication personnel, thereby reducing the amount of useless material that is produced before a process defect can be detected.

摘要： A method includes forming a stress compensation layer over a first side of a semiconductor substrate and forming a Group III-nitride layer over a second side of the substrate. Stress created on the substrate by the Group III-nitride layer is at least partially reduced by stress created on the substrate by the stress compensation layer. Forming the stress compensation layer could include forming a stress compensation layer from amorphous or microcrystalline material. Also, the method could include crystallizing the amorphous or microcrystalline material during subsequent formation of one or more layers over the second side of the substrate. Crystallizing the amorphous or microcrystalline material could occur during subsequent formation of the Group III-nitride layer and/or during an annealing process. The amorphous or microcrystalline material could create no or a smaller amount of stress on the substrate, and the crystallized material could create a larger amount of stress on the substrate.

摘要： A methodology for regulating power supplied to a powered component based on hardware performance, such as may be used in a system that includes the powered component and a switching regulator (EMU or energy management unit) configured to supply a regulated supply voltage to the powered component. Performance monitoring circuitry generates a performance monitoring signal corresponding to a detected performance level of selected digital operations of the powered component relative to a reference performance level. Switching control circuitry provides a switching control signal in response to the performance monitoring signal. In an example embodiments, the switching control circuitry for the switching regulator (switching transistor) is integrated into the powered component, and the detected performance level corresponds to a detected signal path delay associated with the digital operations of the powered component.

摘要： A wireless power transfer system includes: a non-resonant transmitter, or a transmitter with a resonant circuit; and a non-resonant receiver, or a receiver with a resonant circuit. In some implementations, a transmitter with a resonant circuit is operated away from its resonance frequency. In some implementations, a receiver with a resonant circuit is operated away from the transmitter resonance frequency and/or the transmitter operating frequency. In some implementations, the selection of receiver resonance frequency is based on receiver power requirements. Thus, wireless power transfer may be accomplished by operating away from resonance in a quasi-resonant or non-resonant mode, and further may be accomplished using a non-resonant transmitter and/or a non-resonant receiver. Effective power transfer may also be achieved between a transmitter and multiple receivers. A combination of resonant and non-resonant transmitter and receiver(s) may be used for power transfer.
