摘要： 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.

摘要： Modulation circuitry is configured to generate a phase modulated signal having an output frequency that corresponds to a local oscillator (LO) signal divided by N.5. A phase locked loop (PLL) is configured to generate an LO signal having a frequency that is N.5 times the output frequency. Pulse circuitry configured to generate, based at least on a value of N, an edge signal including a pulse aligned with a positive edge of the LO signal and a pulse aligned with a negative edge of the LO signal. The edge signal is used to generate the phase modulated signal.

摘要： This document discusses apparatus and methods for reducing energy consumption of digital-to-time converter (DTC) based transmitters. In an example, a wireless device can include a digital-to-time converter (DTC) configured to receive phase information from a baseband processor and to provide a first modulation signal for generating a wireless signal, and a detector configured to detect an operating condition of the wireless device and to adjust a parameter of the DTC in response to a change in the operating condition.

摘要： A digital to time converter (DTC). The DTC includes a lookup table, a divider, a thermometric array and a switched capacitor array. The lookup table is configured to generate one or more corrections based on thermometric bits of an input signal. The divider is configured to generate a plurality of divider signals from an oscillator signal based on the one or more corrections. The thermometric array is configured to generate a medium approximation signal from the plurality of divider signals based on the one or more corrections. The switched capacitor array is configured to generate a digital delay signal from the medium approximation signal based on the one or more corrections and switched capacitor bits of the input signal.
