Abstract: This document discusses apparatus and methods for compensating non-linearity of digital-to-time converters (DTCs). In an example, a wireless device can include a digital-to-time converter (DTC) configured to receive a phase data information from a baseband processor and to provide a first modulation signal for generating a wireless signal, a detector configure to receive the first modulation signal and provide an indication of nonlinearities of the DTC, and a pre-distortion module configured to provide pre-distortion information to the DTC using the indication of nonlinearities.

Abstract: This application discusses, among other things, apparatus and methods for sharing a local oscillator between multiple wireless devices. In certain examples, an apparatus can include a central frequency synthesizer configured to provide a central oscillator signal having a first frequency, a first transmitter, the first transmitter including a first transmit digital-to-time converter (DTC) configured to receive the central oscillator signal and to provide a first transmitter signal having a second frequency, and a first receiver, the first receiver including a first receive DTC configured to receive the central oscillator signal and to provide a first receiver signal having a first receive frequency.

Abstract: A digital phase locked loop operates with a time-to-digital converter and an a-priori-probability-phase-estimation component or estimator component that estimates the un-quantized phase associated with a quantization output of the time-to-digital converter. The time-to-digital converter generates a quantized value as the quantization output from a local oscillator signal of a local oscillator and a reference signal of a reference clock. The estimation component estimates a phase value from the quantized values as a function of a-priori data related to the time-to-digital converter and boundaries of the quantized value.
