    摘要： An apparatus for interpolating between a first and a second signal is provided. The apparatus includes a plurality of interpolation cells coupled to a common node of the apparatus. Further, the apparatus includes a control circuit configured to supply, based on a control word, respective selection signals to each of the plurality of interpolation cells. At least one of the plurality of interpolation cells is configured to couple the common node to a first potential if the first signal and the second signal are both at a first signal level, couple the common node to a second potential, which is different from the first potential, if the first signal and the second signal are both at a second signal level, which is different from the first signal level, and to decouple the common node from at least one of the first potential and the second potential if the first signal and the second signal are at different signal levels. Additionally, the at least one of the plurality of interpolation cells is configured to switch, based on a state indicated by the respective selection signal, to coupling the common node to the second potential in response to a transition of either the leading one or the trailing one of the first signal and the second signal from the first signal level to the second signal level.

    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.
