  • Patent number: 8325756
    Abstract: Aspects of a method and system for a power reduction scheme for Ethernet PHYs are provided. An Ethernet PHY in a link partner may disable transmission via a transmit DAC integrated during an inactive connection, 10Base-T autonegotiation operation, and/or active 10Base-T connection with no data packet transmission. The DAC may be a voltage mode or current mode DAC. The PHY or a MAC device may determine when to disable transmission via the DAC. In this regard, the PHY or the MAC device may generate appropriate signals for disabling the transmission. The DAC may be enabled for transmission by the PHY or the MAC device when a connection becomes active or when an active 10Base-T connection is ready to transmit data. Moreover, the PHY may enable transmission via the DAC when operating in a forced 10Base-T mode of operation and the connection to the link partner is active.

  • Patent number: 8314002
    Abstract: A semiconductor device is formed in a thin float zone wafer. Junctions are diffused into the top surface of the wafer and the wafer is then reduced in thickness by removal of material from its bottom surface. A weak collector is then formed in the bottom surface by diffusion of boron (for a P type collector). The weak collector is then formed or activated only over spaced or intermittent areas. This is done by implant of the collector impurity through a screening mask; or by activating only intermittent areas by a laser beam anneal in which the beam is directed to anneal only preselected areas. The resulting device has an effective very low implant dose, producing a reduced switching energy and increased switching speed, as compared to prior art weak collector/anodes and life time killing technologies.

  • Patent number: 8309951
    Abstract: In one disclosed embodiment, the present test structure for determining gate-to-body current in a floating body FET includes a floating body FET situated over a semiconductor layer, where the floating body FET includes a first gate and first and second source/drain regions. The floating body test structure further includes a second gate and a first contact situated over the first source/drain region. A gate-to-channel current measured between the second gate and the first contact is utilized to determine the gate-to-body tunneling current. The gate-to-body tunneling current can be determined by subtracting the gate-to-channel current from twice a source/drain current of the floating body FET. The test structure may also include a second contact situated on a doped region in the semiconductor layer, where a diode current flow through the doped region determines a body voltage for the floating body FET.
