摘要： A particular device includes a substrate and a spiral inductor coupled to the substrate. The spiral inductor includes a first conductive spiral and a second conductive spiral overlaying the first conductive spiral. A first portion of an innermost turn of the spiral inductor has a first thickness in a direction perpendicular to the substrate. The first portion of the innermost turn includes a first portion of the first conductive spiral and does not include the second conductive spiral. A second portion of the innermost turn includes a first portion of the second conductive spiral. A portion of an outermost turn of the spiral inductor has a second thickness in the direction perpendicular to the substrate that is greater than the first thickness. A portion of the outermost turn includes a second portion of the first conductive spiral and a second portion of the second conductive spiral.

摘要： Techniques for detecting other stations in a power efficient manner are described. A station may operate in a passive mode or a search mode. In the passive mode, the station receives for one receive period in each time interval. In the search mode, the station transmits for a series of transmit periods in one time interval, then receives for one receive period in the next time interval, and repeats the transmit/receive cycle. In an example scenario, station A operates in the search mode and sends a series of transmissions during its transmit periods. Station B operates in the passive mode, receives a transmission from station A during its receive period, switches to the search mode, and sends a series of transmissions for one time interval. Station A receives a transmission from station B during its receive period. After detecting one another, stations A and B may perform synchronization.

摘要： A diplexer includes a substrate having a set of through substrate vias. The diplexer also includes a first set of traces on a first surface of the substrate. The first traces are coupled to the through substrate vias. The diplexer further includes a second set of traces on a second surface of the substrate that is opposite the first surface. The second traces are coupled to opposite ends of the set of through substrate vias. The through substrate vias and the traces also operate as a 3D inductor. The diplexer also includes a capacitor supported by the substrate.

摘要： Techniques for adaptively tuning an impedance matching circuit are disclosed. In an aspect, the impedance matching circuit is pre-characterized. The performance of the impedance matching circuit is determined for multiple settings of the impedance matching circuit, stored in memory, and used to tune the impedance matching circuit. In another aspect, the impedance matching circuit is tuned based on measurements for one or more parameters such as delivered power, return loss, power amplifier current, antenna/load impedance, etc. In an exemplary design, an apparatus includes a memory and a control unit. The memory stores information for multiple settings of an impedance matching circuit. The control unit selects one of the multiple settings of the impedance matching circuit based on the information for the multiple settings and measurements for the impedance matching circuit. The impedance matching circuit performs impedance matching for a load circuit (e.g., an antenna) based on the selected setting.

摘要： Reconfigurable impedance matching circuits with multiple configurations are disclosed. A reconfigurable impedance matching circuit may be implemented with a set of reactive elements (e.g., inductors and/or capacitors) and a set of switches. Different configurations may be obtained with different settings of the switches and may be associated with different impedance tuning curves. This may enable the reconfigurable impedance matching circuit to provide better impedance matching for a load circuit (e.g., an antenna). In an exemplary design, the reconfigurable impedance matching circuit includes at least one variable reactive element configured to tune the impedance of the reconfigurable impedance matching circuit in order to provide better impedance matching. In an exemplary design, the reconfigurable impedance matching circuit may include at least one reconfigurable reactive element, each of which can be connected as a series element or a shunt element.
