Abstract: Various aspects provide a radiohead circuit and a communication device including the radiohead circuit. In an example, the radiohead circuit includes an antenna interface, a radio frequency front end configured to receive a wireless communication signal via the antenna interface, and a processor configured to perform an initial signal detection to detect if a wireless communication signal has been received based on whether a signal the processor received from the radio frequency front end fulfill a predefined radiohead circuit detection criterion, generate an initial signal detection information comprising an information as to whether the wireless communication signal has been received based on the initial signal detection; and provide the initial signal detection information to a communication interface for a final signal detection; the communication interface configured to couple the processor to a radiohead circuit-external processor external to the radiohead circuit.

Abstract: An apparatus for generating an oscillation signal is provided. The apparatus includes a first oscillator configured to generate a first reference oscillation signal, and a second oscillator configured to generate a second reference oscillation signal. A frequency accuracy of the first oscillator is higher than a frequency accuracy of the second oscillator. Further, an oscillator phase noise of the second oscillator is lower than an oscillator phase noise of the first oscillator. The apparatus further includes a processing circuit configured to generate a third reference oscillation signal based on the first reference oscillation signal and the second reference oscillation signal. Additionally, the apparatus includes a phase-locked loop configured to generate the oscillation signal based on the third reference oscillation signal. A frequency of the oscillation signal is a multiple of a frequency of the third reference oscillation signal.

Abstract: Techniques are described related to digital radio control, partitioning, and operation. The various techniques described herein enable high-frequency local oscillator signal generation and frequency multiplication using radio-frequency (RF) digital to analog converters (RFDACs). The use of these components and others described throughout this disclosure allow for the realization of various improvements. For example, digital, analog, and hybrid beamforming control are implemented and the newly-enabled digital radio architecture partitioning enables radio components to be pushed to the radio head, allowing for the omission of high frequency cables and/or connectors.

Abstract: A digital to time converter (DTC) system is disclosed. The DTC system comprises a DTC circuit configured to generate a DTC output clock signal at a DTC output frequency, based on a DTC code. In some embodiments, the DTC system further comprises a calibration circuit comprising a period error determination circuit configured to determine a plurality of period errors respectively associated with a plurality consecutive edges of the DTC output clock signal. In some embodiments, each period error of the plurality of period errors comprises a difference in a measured time period between two consecutive edges of the DTC output clock signal from a predefined time period. In some embodiments, the calibration circuit further comprises an integral non-linearity (INL) correction circuit configured to determine a correction to be applied to the DTC code based on a subset of the determined period errors.

Abstract: A divider-less fractional digital phase locked loop (PLL) is disclosed and can include a time-to-digital converter (TDC) to receive a reference clock signal and a digitally control oscillator (DCO) clock signal, and generate a phase difference signal based on the reference clock signal and the DCO clock signal. A counter coupled in parallel to the TDC can receive the clock signal and count an output frequency of the clock signal to detect reference noise within the reference signal that is above a threshold. A sampler can sample an output of the counter using a replica of the reference signal, and generate a plurality of samples. A sample selector can select one of the plurality of samples based on the phase difference signal. A digital phase detector (DPD) can generate an output phase measurement based on the phase difference signal and the selected sample of the plurality of samples.
