Abstract: A subsampling motion detector configured to detect motion information of an object under measurement receives a first wireless radio frequency (RF) signal and transmits a second wireless RF signal, the first wireless RF signal being generated by reflecting the second wireless RF signal from the object. The subsampling motion detector includes a controllable oscillator outputting an oscillation signal, wherein the first wireless RF signal is injected to the controllable oscillator for controlling the controllable oscillator through injecting locking. The subsampling motion detector further including a subsampling phase detector (SSPD) generating a control signal according to the oscillation signal generated by the controllable oscillator and a reference frequency, the SSPD outputting the control signal to the controllable oscillator for controlling the controllable oscillator, the oscillation signal of the controllable oscillator being locked to a multiple of the reference frequency and the control signal representing the motion information of the object.

Abstract: A detector includes a frequency multiplier and a transceiving node. The frequency multiplier includes a first terminal, a second terminal and an output terminal. The first terminal is used to receive a first injection signal having a first frequency. The output terminal is used to output an output signal. The second terminal is used to receive a second injection signal having a second frequency. The frequency multiplier is used to output the output signal at a frequency substantially equal to a multiple of the first frequency by injection locking and pull the output signal to the second frequency by injection pulling. The transceiving node is coupled to the output terminal and the second terminal of the frequency multiplier. The transceiving node is used to transmit the output signal, and receive a received signal having a third frequency. The received signal is used to update the second injection signal.

Abstract: A subsampling motion detector used to detect motion information of an object under measurement receives a first wireless radio frequency (RF) signal and transmits a second wireless RF signal, the first wireless RF signal being generated by reflecting the second wireless RF signal from the object. The subsampling motion detector has a high frequency oscillator for outputting a high frequency oscillation signal, a low frequency controllable oscillator for generating a low frequency oscillation signal according to a control signal, and a subsampling analog-to-digital converter (SSADC). The SSADC detects a phase difference between the high frequency oscillation signal and the low frequency oscillation signal at time periods indicated by the low frequency oscillation signal. The SSADC outputs a phase detection digital output signal according to the detected phase difference. The control signal is generated and the motion information of the object is calculated according to the phase detection digital output signal.
