    Abstract: A switching power supply in which the oscillation frequency is dynamically controlled to have an instantaneous frequency value which is reduced when the power line waveform is near its peaks. This is preferably accomplished by a divider circuit, which provides an output current proportional to the ratio between the instantaneous value of the rectified voltage and the long-term-averaged value of that voltage. This output current is fed into a ramp generator, to dynamically shift the frequency of the ramp generator as the output current changes. This circuit is indifferent to power line voltage and frequency (over a fairly wide range), and therefore may be used in different countries having different power standards.

    Abstract: A method for measuring the degree of planarity in an integrated circuit includes depositing, onto a dielectric layer to be measured for planarity, a predetermined measure path of a conductive film and measuring the electric resistance of said measure path. The resistance of such a measure path is minimal where the surface on which it has been deposited is perfectly planar, and increases with the surface deviation from perfect planarity. An integrated circuit containing a measurement portion of conductive film and a reference portion of conductive film is described.

    Abstract: A circuit for regulating the charging time of the output node of an amplifier at start up. The output node commonly comprises an external soft-start capacitor charged by a current delivered by a pull-up transistor of a push-pull output stage of the amplifier, through a decoupling diode that is functionally connected between the output node of the amplifier and a terminal of the external soft-start capacitor. The present application provides a current mirror feed back circuit capable of mirroring the charge current of the external soft-start capacitor onto the driving node of the pull-up transistor of the output stage of the amplifier. The regulating circuit permits use of an external capacitance of extremely small size. Upon the reaching of a fully charged condition by the external capacitor, the control circuit self-isolates and does not influence in any way the normal operation of the amplifier.

    Abstract: For detecting the position of a magnetic element having a field component zeroing in at least one point in space, typically in a plane, a plurality of elementary Hall-effect sensors are integrated side by side and aligned in a direction perpendicular to the zeroing field component and to the current flowing through the elementary sensors. The elementary sensor generating a zero output voltage therefore indicates the zero position of the field component and consequently the position of the magnetic element with respect to the position sensor, so that The outputs of the elementary sensors provide a quantized numeric code indicating the position of the magnetic element.

    Abstract: A circuit device for recovering energy from an inductive load is connected to a protection circuit for protecting a driver circuit from a charge contained in the inductive load. The inductive load is connected between a power supply line at one end and the driver circuit and protection circuit at another end. The circuit device has a charge accumulator, preferably a capacitor, connected to the protection circuit for accumulating charge from the inductive load. A control circuit monitors the level of charge in the capacitor. A switch, connected between the capacitor and the power supply line, permits the charge accumulated in the capacitor to discharge into the power supply line. The control circuit controls the switch so as to permit the intermittent discharge of the inductive load: the switch is opened to permit charge from the inductive load to accumulate in the capacitor; and, the switch is closed to permit the capacitor to discharge the accumulated charge to the power supply line.
