  • Publication number: 20150325645
    Abstract: Disclosed are methods and resulting structures which provide an opening for epitaxial growth, the opening having an associated projection for reducing the size of the contact area on a substrate at which growth begins. During growth, the epitaxial material grows vertically from the contact area and laterally over the projection. The projection provides a stress relaxation region for the lateral growth to reduce dislocation and stacking faults at the side edges of the grown epitaxial material.

  • Publication number: 20140320104
    Abstract: A circuit for controlling a switched-mode DC-DC converter. An inductor is connected between a switching node and an output node, and an output capacitor is connected in series with the inductor. An RC circuit is connected in parallel with the inductor to compensate for ripple voltage. In a discontinuous current mode, a pulse is applied to the switching node and then removed. In this mode, an RC time constant for the RC circuit is increased during the falling edge of a difference signal such that the difference signal does not drop below zero.

  • Publication number: 20140239924
    Abstract: A voltage converter (FIG. 4) for a power supply circuit is disclosed. The voltage converter comprises a control circuit (400) coupled to receive an enable (EN) signal. The control circuit produces a first control signal (PWM) to provide a load current (IL) in response to the enable signal. A sample and hold circuit (408) is arranged to produce a third control signal (CSP) to emulate the load current and a fourth control signal (CSN?) to sample and hold value of the third control signal. A comparator circuit (416) is arranged to compare the third and fourth control signals and produce the enable signal in response to a result of the comparison.

  • Publication number: 20090316703
    Abstract: A modem and communication method between a wide area network (WAN) and a client device receives a communication data packet from the WAN or the client device, and removes a virtual local area network identification (VLAN ID) of the communication data packet in response to a determination that a VLAN ID of the communication data packet does not identify a local area network port of the modem. The modem and communication method further translates an IP address of the communication data packet having no VLAN ID, and transmits the translated communication data packet to the client device or the WAN using a network access translation port of the modem. Furthermore, the modem and communication method transmits the communication data packet containing the VLAN ID to the client device or the WAN using the LAN port.
