WIRELESS COMMUNICATION DEVICE, INTEGRATED CIRCUIT AND WIRELESS COMMUNICATION METHOD

WIPO Patent Application WO/2016/027742

A1

[Problem] To simplify an internal configuration to achieve low power consumption. [Solution] A wireless communication device is provided with: an analog control loop unit; a digital control loop unit; a voltage controlled oscillator for generating a voltage-controlled oscillating signal on the basis of an analog control signal and a digital control signal; a data slicer for generating a digital signal obtained by digitally demodulating a reception signal, on the basis of a result that is obtained by comparing the digital control signal with a prescribed threshold value; an automatic offset control unit for generating a correction signal according to an error between a frequency of the reception signal and a frequency of the voltage-controlled oscillation signal on the basis of the time difference between a timing when the digital control signal becomes identical to the threshold value of the data slicer and a pre-determined reference timing; and a set code regulator for regulating a frequency set code signal on the basis of the correction signal, wherein a gain of the digital control loop unit is higher than that of the analog control loop unit.
