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： 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.

摘要： Die-to-die interconnect structures are leveraged to form the inductive component of an LC oscillator, thus yielding an LC tank distributed across multiple IC dies rather than lumped in a single die. By this arrangement, reliance on area/power-consuming on-chip inductors may be reduced or eliminated, and phase-aligned clocks may be extracted from the LC tank within each of the spanned IC dies, obviating multiple oscillator instances or complex phase alignment circuitry.

摘要： A phase detector circuit compares the phases of first and second periodic input signals to generate an output signal. The phase detector includes a circuit that makes two different combinations of the first and the second periodic input signals to generate third and fourth periodic signals. This circuit causes the third periodic signal to be based on a first combination of the first periodic signal and the second periodic signal that imparts a first relative phase shift. The circuit causes the fourth periodic signal to be based on a second combination of the first periodic signal and the second periodic signal to provide a different relative phase shift. The phase detector also includes a comparison circuit that compares a measure of the power of the third periodic signal to a measure of the power of the fourth periodic signal to generate the phase comparison output signal.
