Abstract
A sub-sampling phase-locked loop is described, which comprises a digital-to-time converter, a sampler module, an interpolator, and a voltage controlled oscillator. The digital-to-time converter is configured to provide a first delay signal SDLYat a first point tin time and a second delay signal SDLYat a second point in time t. The sampler module is configured to provide a first sample Sof the oscillator output signal SOUT at the first point in time tand a second sample Sof the oscillator output signal SOUT at the second point in time t. The interpolator is configured to provide a sampler signal SSAMPL by interpolating the first sample Sand the second sample S. The voltage controlled oscillator is configured to control the oscillator output signal SOUT based on the sampler signal SSAMPL.
