Abstract

The present application relates to a phase adjustment device and a system for extracting a terahertz signal. A phase adjustment device, which is characterized in comprising: a phase-locked loop module used for receiving a reference signal so as to output an oscillator signal and a demodulator signal; a frequency dividing module used for receiving the oscillator signal so as to output a phase shift signal and a frequency division signal; and a frequency tracking module used for receiving the demodulator signal so as to output a capture range signal, wherein the phase-locked loop module is further used for receiving the frequency division signal and the capture range signal. The foregoing phase adjustment device may control the operation of the phase-locked loop module by means of the frequency tracking module outputting the capture range signal so that the phase-locked loop module may automatically capture and lock a wide range of terahertz signals, thereby outputting a phase shift signal having high precision and stability.

Description

technical field [0001] The invention relates to the field of electronic circuits, in particular to a phase adjustment device and a terahertz signal extraction system. Background technique [0002] Terahertz signals currently have broad application prospects in many fields. The traditional terahertz signal acquisition process generally uses an antenna as a signal receiving end, and the received signal is amplified by a preamplifier before data acquisition. Such an acquisition process will be accompanied by relatively large noise and interference signals, and it is difficult to capture terahertz signals from signals masked by noise. Contents of the invention [0003] Based on this, it is necessary to provide a phase adjustment device and a terahertz signal extraction system for the above technical problems, which can automatically capture and lock a wide range of terahertz signals, and output a phase-shifted signal with high precision and stability. [0004] A phase adjustm...
