Abstract:
A wireless communication apparatus has an analog control loop circuitry to generate an analog control signal which adjusts a phase of a voltage-controlled oscillation signal, an integrator to integrate the analog control signal, a phase adjuster to adjust a phase of the voltage-controlled oscillation signal, a digital control loop circuitry, in a first mode, to match a frequency of the voltage-controlled oscillation signal to a frequency of the received signal based on an output signal of the phase adjuster, and in a second mode, to generate a digital control signal which is opposite in phase to the analog control signal and has a frequency, a voltage-controlled oscillator to generate the voltage-controlled oscillation signal based on the analog and digital control signals, and a signal switch to supply the analog control signal to the integrator in the first mode and to the voltage-controlled oscillator in the second mode.
