Abstract: A novel and useful radio frequency (RF) front end module (FEM) circuit that provides high linearity and power efficiency and meets the requirements of modern wireless communication standards such as 802.11 WLAN, 3G and 4G cellular standards, Bluetooth, ZigBee, etc. The configuration of the FEM circuit permits the use of common, relatively low cost semiconductor fabrication techniques such as standard CMOS processes. The FEM circuit includes a power amplifier made up of one or more sub-amplifiers having high and low power circuits and whose outputs are combined to yield the total desired power gain. An integrated multi-tap transformer having primary and secondary windings arranged in a novel configuration provide efficient power combining and transfer to the antenna of the power generated by the individual sub-amplifiers.

Abstract: A single-crystal pulling device includes vertically tilted magnetic coils between the walls of a cooling vessel. The inside and outside walls of the cooling vessel are coaxially aligned about a central axis. The inside wall of the cooling vessel is coaxially disposed around a cylindrical crucible that holds molten semiconductor material. A mid line passes through the middle point of a first coil, the central axis and the middle point of a second coil. The first coil is wound in a first plane, and the second coil is wound in a second plane. The first plane and the second plane both intersect the central axis at the same point. The first plane intersects the central axis at an angle between 5 and 15 degrees. In one embodiment, the first plane intersects the central axis below the crucible. In another embodiment, the first plane intersects the central axis above the crucible.

Abstract: A power feeding coil unit includes a power feeding coil, and an auxiliary coil. The auxiliary coil is arranged not to interlink with a magnetic flux that interlinks with a power receiving coil that is arranged to face the power feeding coil during power feeding. An axial direction of the auxiliary coil is nonparallel to an opposing direction of the power feeding coil and the power receiving coil. A direction of circulation of a magnetic flux generated by the auxiliary coil is opposite to a direction of circulation of a magnetic flux generated by the power feeding coil.
