| 20100308924 | APPARATUS AND METHOD FOR FREQUENCY GENERATION - A wideband frequency generator has two or more oscillators for different frequency bands, disposed on the same die within a flip chip package. Coupling between inductors of the two oscillators is reduced by placing one inductor on the die and the other inductor on the package, separating the inductors by a solder bump diameter. The loosely coupled inductors allow manipulation of the LC tank circuit of one of the oscillators to increase the bandwidth of the other oscillator, and vice versa. Preventing undesirable mode of oscillation in one of the oscillators may be achieved by loading the LC tank circuit of the other oscillator with a large capacitance, such as the entire capacitance of the coarse tuning bank of the other oscillator. Preventing the undesirable mode may also be achieved by decreasing the quality factor of the other oscillator's LC tank and thereby increasing the losses in the tank circuit. | 12-09-2010 |

| 20110110463 | RECEIVER WITH BALANCED I/Q TRANSFORMER - A receiver with a balanced I/Q transformer is described. In an exemplary design, the receiver includes an LNA that amplifies a received RF signal and provides a single-ended RF signal to the balanced I/Q transformer. The balanced I/Q transformer includes at least one primary coil and first and second secondary coils. The first secondary coil is magnetically coupled to the at least one primary coil and provides a first differential RF signal to a first mixer. The second secondary coil is magnetically coupled to the at least one primary coil and provides a second differential RF signal to a second mixer. The first and second mixers downconvert the first and second differential RF signals with I and Q LO signals, respectively, and provide differential I and Q downconverted signals. The primary and secondary coils may be fabricated on two conductive layers of an integrated circuit. | 05-12-2011 |
| 20110128084 | METHODS AND APPARATUS FOR INDUCTORS WITH INTEGRATED PASSIVE AND ACTIVE ELEMENTS - An integrated circuit is described. The integrated circuit includes an inductor that has a large empty area in the center of the inductor. The integrated circuit also includes additional circuitry. The additional circuitry is located within the large empty area in the center of the inductor. The additional circuitry may include a capacitor bank, transistors, electrostatic discharge (ESD) protection circuitry and other miscellaneous passive or active circuits. | 06-02-2011 |

| 20090098831 | DUAL BAND RADIO FREQUENCY TRANSMITTER - A transmitter includes a transformer and a transformer tuning circuit. The transformer transforms a differential radio frequency (RF) signal to a single-ended RF signal. The transformer tuning circuit tunes the transformer to permit the transmitter to transmit the single-ended RF signal in a first frequency band (e.g., cellular frequency band) or a second frequency band (e.g., PCS frequency band). | 04-16-2009 |
| 20100265022 | DUAL INDUCTOR CIRCUIT FOR MULTI-BAND WIRELESS COMMUNICATION DEVICE - This disclosure describes a dual inductor circuit, which may be particularly useful in a mixer of a wireless communication device to allow the mixer to operate for two different frequency bands. The dual inductor circuit comprises an inductor-within-inductor design in which a small inductor is disposed within a large inductor. The two inductors may share a ground terminal, but are otherwise physically separated and independent from one another. Terminals of the inner inductor, for example, are not tapped from the outer inductor, which can reduce parasitic effects and electromagnetic interference relative to tapped inductor designs. The independence of the inductors also allows the different inductors to define different resonance frequencies, which is desirable. | 10-21-2010 |
| 20110105072 | DUAL INDUCTOR CIRCUIT FOR MULTI-BAND WIRELESS COMMUNICATION DEVICE - This disclosure describes a dual inductor circuit, which may be particularly useful in a mixer of a wireless communication device to allow the mixer to operate for two different frequency bands or in a multi-differential branch low noise amplifier wherein each of the differential branches possess a different set of gain and linearity characteristics for a signal operating at the same frequency. The dual inductor circuit comprises an inductor-within-inductor design in which a small inductor is disposed within a large inductor. The two inductors may share a ground terminal, but are otherwise physically separated and independent from one another.

| 20100185205 | INTEROCULAR INJECTOR - An intraocular injector includes a syringe body having open-ended cone disposed in one end thereof along with a piston disposed in the body. A transparent implant holder having a lumen therein is aligned with an open-ended cone, a needle include a proximal end and a distal end with a bevel disposed on the distal end of the needle. A plunger affixed to the piston and slidable within a holder lumen and needle lumen is provided for injecting solid intraocular implants into an eye. A cylindrical syringe body shape facilitates control over the needle bevel orientation during injection of the implant into the eye. | 07-22-2010 |
