Abstract:
A PFD outputs a detection signal based on a phase difference or a frequency difference between a reference signal and a feedback signal, a charge pump circuit outputs a pulse signal based on the detection signal, and a loop filter outputs a control voltage based on the pulse signal. A VCO includes a ring oscillator where a plurality of delay element units, which include a plurality of delay elements (for example, inverter circuits) connected in parallel, are connected in series in a ring, controls the frequency of the output signal of the ring oscillator based on the control voltage, and controls the phase of the output signal of the ring oscillator by controlling the active number of delay elements, out of the plurality of delay elements, based on the detection signal. A frequency divider circuit generates and outputs a feedback signal by dividing the frequency of the output signal.

Claim (Index 2):
The injection-locked PLL circuit according to  claim 1 , wherein\n the voltage-controlled oscillator circuit includes a switch unit that sets, in a first state where a second phase of the feedback signal is a first phase difference behind a first phase of the reference signal and based on the detection signal, first delay elements out of the plurality of delay elements in an operating state for a first period corresponding to the first phase difference, and sets, in a second state where the second phase is a second phase difference ahead of the first phase and based on the detection signal, second delay elements out of the plurality of delay elements in a non-operating state for a second period corresponding to the second phase difference.
