Abstract: A wireless wake-up receiver includes multiple signal chains each signal chain being coupled to continuously receive a signal from a respective antenna and to provide a respective detected pattern at a signal chain output. Each signal chain includes a first path having a mixer-first architecture and operates in a bandpass-mode using differential signals. The wireless wake-up receiver also includes a digital correlator operable to receive the respective detected patterns and to determine whether one of the respective detected patterns is equal to a desired pattern.

Abstract: A long-range power-efficient multiple-band identification system and method includes, for example, a base-station control module and paired electronic key fob. The base-station control module and paired electronic key fob is arranged to provide a UHF (ultra-high frequency) wake transmitter for transmitting a wakeup signal in a UHF frequency range to the paired electronic key. When in range, the electronic key is awakened by the wakeup signal and in response transmits an acknowledgment reply to the base-station control module. After receiving the acknowledgment, the base-station control module transmits a relatively high power localization signal for determining an electronic key location.

Abstract: A system on a chip (SoC) includes a transceiver comprising a transmitter having a power amplifier and a receiver having a signal buffer. At least one of the transmitter and receiver has a configurable portion that can be configured to produce a range of waveforms (both in waveshape as well as duty cycle). A low cost built in self test (BIST) logic is coupled to the transceiver. The BIST logic is operable to calibrate the configurable portion of the transceiver to produce a waveform that has a selected harmonic component that has an amplitude that is less than a threshold value. Current consumed by the transceiver may be dynamically reduced by selecting an optimized waveform that has low harmonic components.

Abstract: A self-calibrating shared-component dual synthesizer includes, for example, two frequency synthesizers that are adapted to operate (respectively) in transmit (TX) and receive (RX) modes. Each synthesizer can be selectively arranged to vary and optimize the phase noise in accordance with the TX and RX requirements associated with each mode as well as independently optimized for flexible low area floorplan to achieve low power, spectral fidelity and reduced test time, low cost built in self-calibration. The two frequency synthesizers are also adapted to provide a built-in self-test signals used for intermodulation testing and calibration.
