    Abstract: A phase interpolator is provided. The phase interpolator includes a plurality of capacitors, a first input for a clock signal, a second input for a phase shifted clock signal, a reference input for a reference signal, and an output. The phase interpolator is configured to provide at its output an interpolated, modulated phase information signal by switching, dependent on a modulation information, a first number of the capacitors between the first input and the output, a second number of the capacitors between the second input and the output, and a third number of the capacitors to the reference input.

    Abstract: Apparatus and methods for a digital-to-time converter (DTC) are provided. In an example, a DTC can include a phase interpolator and a ring oscillator. The phase interpolator can be configured to receive digital representations of two or more distinct phase signals, and to interpolate the digital representations of the two or more distinct phase signals to provide an interpolated output phase signal. The ring oscillator can be configured to receive the interpolated phase signal, to lock on to a frequency and a phase of the interpolated output phase signal, and to provide a filtered phase signal.
