Low-power consumption, high-resolution and all-digital phase-locked loop structure

The invention provides a low-power consumption, high-resolution and all-digital phase-locked loop structure. The low-power consumption, high-resolution and all-digital phase-locked loop structure includes a digital circuit part which comprises at least one numerically-controlled oscillator module, and a logic circuit part which comprises a phase discriminator module, an all-digital phase-locked loop controller module and a frequency dividing module. According to the low-power consumption, high-resolution and all-digital phase-locked loop structure, the numerically-controlled oscillator of a coarse adjustment-and-fine adjustment cascade framework structure is adopted, and therefore, an operating frequency range can be extended, and high accuracy can be maintained; and a plurality of segmented time-delay links form a coarse adjustment part, and therefore, power consumption can be decreased.
