  • Patent number: 7439100
    Abstract: In one embodiment, an encapsulated electronic package includes a semiconductor chip having patterned solderable pads formed on a major surface. During an assembly process, the patterned solderable pads are directly affixed to conductive leads. The assembly is encapsulated using, for example, a MAP over-molding process, and then placed through a separation process to provide individual chip scale packages having flip-chip on lead frame interconnects.

  • Patent number: 7439716
    Abstract: A DC-DC converter and method for compensating for errors in the DC-DC converter. The DC-DC converter includes an inductor coupled for receiving a source of operating voltage through a plurality of switches. The switches are controlled by a control circuit that has first and second circuit paths that are substantially parallel to each other. Each circuit path is comprised of two switched capacitor comparators that are connected in series. The circuit paths function such that during one portion of a clock period one of the circuit paths operates in an error correction mode and the other circuit path operates in a normal mode. During a different portion of the clock period the operational modes of the circuit paths switch. This allows for a calibration interval in a sampled system in which at least one circuit path is always active and responsive to the input signals in a desired manner.

  • Patent number: 7417265
    Abstract: In one embodiment, a Schottky diode structure comprises a Schottky barrier layer in contact with a semiconductor material through a Schottky contact opening. A conductive ring is formed adjacent the Schottky contact opening and is separated from the semiconductor material by a thin insulating layer. Another insulating layer is formed overlying the structure, and a contact opening is formed therein. The contact opening is wider than the Schottky contact opening and exposes portions of the conductive ring. A Schottky barrier metal is formed in contact with the semiconductor material through the Schottky contact opening, and is formed in further+contact with the conductive ring.

  • Patent number: 7400127
    Abstract: A regulator circuit and a method for compensating for sag in the output signal of the regulator circuit. A first comparator is coupled to an input of an oscillator, which oscillator outputs a clock signal and a ramp signal. In accordance with a feedback signal from the output of the regulator circuit, the clock and ramp signals of the oscillator are reset if the output signal sags to an undesirable level. The clock and ramp signals can be reset between active edges of the clock. The reset clock and ramp signals cause the regulator circuit to increase its output voltage to reduce the sag.
