摘要： According to one exemplary embodiment, a BiFET situated on a substrate comprises an emitter layer segment situated over the substrate, where the emitter layer segment comprises a semiconductor of a first type. The HBT further comprises a first segment of an etch stop layer, where the first segment of the etch stop layer comprises InGaP. The BiFET further comprises a FET situated over the substrate, where the FET comprises source and drain regions, where a second segment of the etch stop layer is situated under the source and drain regions, and where the second segment of the etch stop layer comprises InGaP. The FET further comprises a semiconductor layer of a second type situated under the second segment of the etch stop layer.

摘要： A primary housing for a motorcycle engine includes an inner housing that defines internal coupling apertures, transmission coupling apertures, and external coupling apertures. Internal fasteners extend through the internal coupling apertures and the transmission coupling apertures to couple the inner housing to the crankcase and the transmission. An outer housing defines coupling apertures that align with the external coupling apertures and fasteners extend through the coupling apertures, through the external coupling apertures, and into the engine crankcase to couple the inner and outer housings to the crankcase. A resonant damping device is rigidly or moveably coupled to an anti-node region of the outer housing to reduce noise emissions from the outer housing during engine operation.

摘要： Disclosed is a multi-phase pulse width modulated voltage regulator and method in which transient voltage excursions or deviations that exceed the load line voltage by more than a pre-determined amount are detected by an ATR circuit and a correction signal is applied. The correction signal is in the form of asynchronous pulses and the number of such pulses is a function of the magnitude of the voltage excursion as determined by the number of thresholds that are exceeded. Also disclosed is an adaptive voltage positioning (AVP) circuit and method for early detection of a transient event by sensing voltage changes at the load and adjusting the target voltage with pre-determined current values prior to the time that ATR event changes in the current at the load are detected. The AVP load line is pre-positioned for more precise current control. Also disclosed is an adaptive filter with adjustable frequency characteristics in response to an ATR event. Also disclosed is a pulse limiting circuit. Also disclosed is a tri-state implementation. Response to transient events is further improved with an external ATR circuit coupled to the load.

摘要： A bipolar junction transistor (BJT) requires the fabrication of a BJT structure and of a support post which is adjacent to, but physically and electrically isolated from, the BJT structure. The BJT structure includes a semi-insulating substrate, a subcollector, a collector, a base, and an emitter. Metal contacts are formed on the subcollector and emitter to provide collector and emitter terminals. Contact to the structure's base is accomplished with a metal contact which extends from the top of the support post to the edge of the base nearest the support post. The contact bridges the physical and electrical separation between the support post and the base and provides a base terminal for the device. The base contact need extend over the edge of the base by no more than the transfer length associated with the fabrication process. This results in the smaller base contact area over the collector than would otherwise be necessary, and a consequent reduction in base-collector capacitance. The invention is particularly useful when forming heterojunction bipolar transistors (HBTs), built on a compound semiconductor substrate such as indium phosphide (InP).

摘要： Disclosed is a power regulator for providing precisely regulated power to a microelectronic device such as a microprocessor. Improved power regulation is accomplished by optimizing the power efficiency of the power regulator. In particular, in a multiphase system, the number of active phases is increased or decreased to achieve optimum power efficiency. The multiphase voltage regulator adapts the operating mode to maximize efficiency as the load current demand of the load device changes by adjusting the number of active phases to maximize efficiency. The total value of current provided by the regulator and the total number of active phases is determined, the total number of active phases is compared with the number of active phases required to provide the total value of current at maximum efficiency; and the number of active phases is adjusted to provide the total value of current at maximum efficiency. A current sense circuit senses the current at each phase, a summing circuit coupled to the output of the current sense circuit provides the total current value of all the measured phases, a circuit coupled to the output of the summing circuit provides the time averaged total current value to a threshold detecting circuit that determines the number of phases at which the voltage regulator should be operating for maximum efficiency, and a circuit for comparing the number of phases that are operating to the number of phases at which the voltage regulator should be operating adjusts the number of active phases to the number of phases at which the voltage regulator should be operating for maximum efficiency.
