Patent number: 9509168Abstract: The embodiments described herein provide a power transmitter for wireless charging of an electronic device and methods of its operation. The power transmitter uses an inverter configured to generate a square wave from a potentially wide ranging DC input voltage. The inverter is configured to generate the square wave with a duty cycle that results in a desired equivalent voltage output, effectively independent of the DC input voltage that is provided. Thus, by generating a square wave with a selectable duty cycle the inverter provides the ability to facilitate wireless power transfer with a wide range of DC input voltages. Furthermore, in some embodiments the power transmitter may provide improved power transfer efficiency using a quasi-resonant phase shift control strategy with adjustable dead time and a matching network that is dynamically selectable to more effectively couple with the transmitter coil combination being used to transmit power to the electronic device.Type: GrantFiled: November 18, 2013Date of Patent: November 29, 2016Assignee: FREESCALE SEMICONDUCTOR, INC.Inventors: Wanfu Ye, Xiang Gao, Chongli Wu

Patent number: 9508599Abstract: Low Q associated with passive components of monolithic integrated circuits (ICs) when operated at microwave frequencies can be avoided or mitigated using high resistivity (e.g., ?100 Ohm-cm) semiconductor substrates and lower resistance inductors for the IC. This eliminates significant in-substrate electromagnetic coupling losses from planar inductors and interconnections overlying the substrate. The active transistor(s) are formed in the substrate proximate the front face. Planar capacitors are also formed over the front face (63) of the substrate. Various terminals of the transistor(s), capacitor(s) and inductor(s) are coupled to a ground plane on the rear face of the substrate using through-substrate-vias to minimize parasitic resistance. Parasitic resistance associated with the planar inductors and heavy current carrying conductors is minimized by placing them on the outer surface of the IC where they can be made substantially thicker and of lower resistance.Type: GrantFiled: April 22, 2015Date of Patent: November 29, 2016Assignee: FREESCALE SEMICONDUCTOR, INC.Inventors: Paul W.

Patent number: 9509310Abstract: A driver circuit configured to produce a pair of output signals from a pair of input signals. The proposed solution brings improvements over conventional LVDS and subLVDS driver circuits because it enables the use of a single driver circuit (also known as “buffer”) which is compliant with both LVDS and subLVDS transmission standards. This allows flexibility with MCUs for instance the automotive industry. Further, proposed solution has the advantage of saving die size in comparison to a solution where two buffers would have been used for different transmission standards. Further, high speed transmission rate is maintained since transmission is performed for one standard at the time. An integrated circuit, a printed circuit and a data processing circuit are also claimed.Type: GrantFiled: February 25, 2016Date of Patent: November 29, 2016Assignee: Freescale Semiconductor, Inc.Inventors: Birama Goumballa, Cristian Pavao-Moreira, Didier Salle

Patent number: 9507373Abstract: An oscillator circuit of the type comprising a flip-flop for generating a clock signal and two comparators for comparing a reference voltage with the voltage across a first capacitor which is charged during a first cycle of the clock signal and the voltage across a second capacitor which is charged during a second cycle of a clock signal provides a means for removing the effects of any offset in either comparator. This is achieved by reversing the inputs of the comparators for each cycle of the output frequency. Thus an offset in a comparator which would increase the clock period on one cycle will reduce the period of the next cycle by the same amount. As a net result, the period of time over two clock periods will stay constant regardless of any offset drift in a comparator.Type: GrantFiled: July 4, 2013Date of Patent: November 29, 2016Assignee: Freescale Semiconductor, Inc.Inventors: Hubert Bode, Dirk Wendel
