US International Trade Commission (ITC) has launched San Diego, CA-based mobile chipset developer Qualcomm, Inc. issued notice of receipt of complaint. Due to the violation of Section 337 in the Qualcomm complaint, due to the import and sale of some mobile electronic devices, patent infringement and coupertino, CA-based consumer electronics, Giant Apple.
According to a press release from Qualcomm on the complaint filed with ITC, the semiconductor manufacturer is demanding ITC to issue a limited exclusion order, which will stop the import of IPhone products, which will allow Qualcomm or Qualcomm partners.
Qualcomm inventions are in the heart of every IPhone and make better extensions than the modem technologies or cellular standards, “Dual Rosenberg, Executive Vice President and Common Advice in Qualcomm”. Patents we are representing six of the most important technologies in thousands of portfolios, and every important thing for IPhone functions.
Series of patenst by Qualcomm
Title “Programmable streaming processor with mixed precision instruction execution”. The disclosure relates to a programmable streaming processor that is capable of executing mixed-precision (e.g., full-precision, half-precision) instructions using different execution units. The various execution units are each capable of using graphics data to execute instructions at a particular precision level. An exemplary programmable shader processor includes a controller and multiple execution units. The controller is configured to receive an instruction for execution and to receive an indication of a data precision for execution of the instruction. The controller is also configured to receive a separate conversion instruction that, when executed, converts graphics data associated with the instruction to the indicated data precision. When operable, the controller selects one of the execution units based on the indicated data precision. The controller then causes the selected execution unit to execute the instruction with the indicated data precision using the graphics data associated with the instruction.
Title “Low-voltage power-efficient envelope tracker”. Techniques for efficiently generating a power supply are described. In one design, an apparatus includes an envelope amplifier and a boost converter. The boost converter generates a boosted supply voltage having a higher voltage than a first supply voltage (e.g., a battery voltage). The envelope amplifier generates a second supply voltage based on an envelope signal and the boosted supply voltage (and also possibly the first supply voltage). A power amplifier operates based on the second supply voltage. In another design, an apparatus includes a switcher, an envelope amplifier, and a power amplifier. The switcher receives a first supply voltage and provides a first supply current. The envelope amplifier provides a second supply current based on an envelope signal. The power amplifier receives a total supply current including the first and second supply currents. In one design, the switcher detects the second supply current and adds an offset to generate a larger first supply current than without the offset.
Title “Compact and robust level shifter layout design” Method and apparatus for voltage level shifters (VLS) design in bulk CMOS technology. A multi-voltage circuit or VLS that operate with different voltage levels and that provides area and power savings for multi-bit implementation of level shifter design. A two-bit VLS to shift bits from a first voltage level logic to a second voltage level logic. The VLS formed with a first N-well in a substrate. The VLS formed with a second N-well in the substrate, adjacent to a side of the first N-well. The VLS formed with a third N-well in the substrate, adjacent to a side of the first N-well and opposite the second N-well. A first one-bit VLS circuit having a portion formed on the first N-well and a portion formed on the second N-well. A second bit VLS circuit having a portion formed on the first N-well and a portion formed on the third N-well.
Titles “Power tracker for multiple transmits signals sent simultaneously” Techniques for generating a power tracking supply voltage for a circuit (e.g., a power amplifier) are disclosed. The circuit may process multiple transmit signals being sent simultaneously on multiple carriers at different frequencies. In one exemplary design, an apparatus includes a power tracker and a power supply generator. The power tracker determines a power tracking signal based on inphase (I) and quadrature (Q) components of a plurality of transmit signals being sent simultaneously. The power supply generator generates a power supply voltage based on the power tracking signal. The apparatus may further include a power amplifier (PA) that amplifies a modulated radio frequency (RF) signal based on the power supply voltage and provides an output RF signal.
It is reported that Qualcomm can initiate a case of infringement of patents in ITC, when in May Bloomberg reported that close sources close to Qualcomm said that the company is considering the feasibility of registering the complaint of Section 337. For its part, Apple seems like it will also ramp its legal plea against Qualcomm in the case filed in January last. On May 20, Apple filed a revised one-time complaint in this case, which was refuting Apple’s claim in this matter, and on the basis of increasing evidence of QLCom’s illegal business model and increasing “new” And came with extended claims. It is difficult to see that the tech licensing company whose techniques have increased mobile processing speed up to 500 times from the initial 3G cellular devices to today’s smartphones, but it would be interesting to see that Apple’s logic is still in spite of this.
