摘要： Embodiments of a circuit are described. In this circuit, a modulation circuit provides a first modulated electrical signal and a second modulated electrical signal, where a given modulated electrical signal, which can be either the first modulated electrical signal or the second modulated electrical signal, includes minimum-shift keying (MSK) modulated data. Moreover, a first phase-adjustment element, which is coupled to the modulation circuit, sets a relative phase between the first modulated electrical signal and the second modulated electrical signal based on a phase value of the first phase-adjustment element. Additionally, an output interface, which is coupled to the first phase-adjustment element, is coupled to one or more antenna elements which output signals. These signals include a quadrature phase-shift-keying (QPSK) signal corresponding to the first modulated electrical signal and the second modulated electrical signal.

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.

摘要： The disclosed embodiments generally relate to techniques for processing signals received from multiple antennas. More specifically, the disclosed embodiments relate to a system that uses an integrated phase-shifting-and-combining circuit to process signals received from multiple antenna elements. This circuit applies a specified phase shift to the input signals, and combines the phase-shifted input signals to produce an output signal. In some embodiments, the integrated phase-shifting-and-combining circuit uses a current-steering mechanism to perform the phase-shifting-and-combining operations. This current-steering mechanism operates by converting the input signals into associated currents, and then steering each of the associated currents through multiple pathways which have different delays. Next, the currents from the multiple pathways for the associated currents are combined to produce the output signal. During this process, while steering each of the associated currents through multiple pathways to achieve different phase shifts, complementary impedance changes through the multiple pathways cause the aggregate impedance at the output to remain substantially constant.
