摘要： An electronic device for wirelessly tracking the position of a second electronic device is disclosed. The electronic device includes transceiver circuitry having a beacon generator to generate a beacon at a particular frequency and direction. An antenna array transmits the beacon, and receives at least one reflected beacon from the second electronic device. The reflected beacon is received if a position of the second electronic device lies within a range of directions of the beacon. The transceiver circuitry further includes an injection-locked oscillator having an input coupled to the antenna array to receive reflected beacons, and to lock to the reflected beacon when the reflected beacon has a frequency value within locking range of the oscillator. Processing circuitry coupled to the transceiver circuitry tracks the position of the second device based on the lock condition of the oscillator.

摘要： The disclosed embodiments relate to the design of a linear equalizer that supports low-power, high-speed data transfers. In some embodiments, this linear equalizer contains a passive network that provides selective frequency peaking in a frequency range associated with a falling edge of a frequency response of the channel. It also includes a level shifter coupled between the channel and the passive network, wherein the level shifter is an active component that provides amplification and/or level-shifting. Moreover, the linear equalizer is designed so that power from the level shifter facilitates the selective frequency peaking of the passive network.

摘要： A gaming system is disclosed comprising a console unit having a processor and transceiver circuitry. The transceiver circuitry couples to the processor and includes respective receiver and transmitter circuits. A first phased array antenna interface is employed to transmit and receive directional signals in response to the processor. The system employs a mobile game controller including a second phased array antenna interface to receive and redirect the directional signals back to the first phased array antenna interface. The processor generates proximity data based at least in part on a parameter associated with the directional signals, the proximity data representing the proximity of the mobile game controller with respect to the game console unit.

摘要： A signal distribution network has segments that each have a buffer circuit, a transmission line coupled to the buffer circuit, an inductor coupled to the buffer circuit through the transmission line, and a variable capacitance circuit coupled to the inductor and coupled to the buffer circuit through the transmission line. A capacitance of the variable capacitance circuit is set to determine a phase and an amplitude of a signal transmitted through the transmission line. A signal distribution network can include a phase detector, a loop filter circuit, and a resonant delay circuit. The phase detector compares a phase of a first periodic signal to a phase of a second periodic signal. The resonant delay circuit has a variable impedance circuit having an impedance that varies based on changes in an output signal of the loop filter circuit.
