Abstract: A detector (200) includes an oscillation source (210), a frequency multiplier (220), a transceiver (230) and a demodulator (240). The oscillation source (210) generates a first injection signal (Vi1) with a first frequency (f1). The frequency multiplier (220) receives the first injection signal (Vi1), outputs an output signal (Vo) and receives a second injection signal (Vi2) with a second frequency (f2). The frequency multiplier (220) uses injection locking to lock a frequency of the output signal (Vo) at a multiple of the first frequency (f1), and uses injection pulling to pull the frequency of the output signal (Vo) to the second frequency (f2). The transceiver (230) transmits the output signal (Vo) and receives a received signal (Vrx) with a third frequency (f3) for updating the second injection signal (Vi2). The demodulator (240) performs a demodulation operation according to the output signal (Vo) so as to generate a displacement signal (Vd).

Abstract: A digital phase-locked loop having a phase frequency detector (PFD), a 3-state phase frequency detection converter (3-state PFD converter), a loop filter and a digital voltage-controlled oscillator is provided. The PFD receives an input frequency and a reference frequency and outputs a first signal and a second signal based on the phase difference between the input frequency and the reference frequency. The 3-state PFD converter outputs a 3-state signal according to the first and second signals, wherein the 3-state signal is presented in 1, 0 and -I. The loop filter outputs at least one control bit based on only the 3-state signal. The DCO adjusts the outputted oscillation frequency according to the control bit.
