Summary:The utility model provides a phase shifter, and relates to the technical field of integrated circuits. The phase shifter comprises a phase frequency detector, a digital charge pump, a digital filter and a numerical control oscillator, the first input end of the phase frequency detector receives an input signal, the first output end of the phase frequency detector is connected with the first input end of the digital charge pump, the second output end of the phase frequency detector is connected with the second input end of the digital charge pump, and the output end of the digital charge pump is connected with the input end of the digital filter. The output end of the digital filter is connected with the input end of the numerically-controlled oscillator, the first output end of the numerically-controlled oscillator outputs digital waveform signals, and the second output end of the numerically-controlled oscillator is connected with the second input end of the phase frequency detector; the digital charge pump,
