Abstract
A quick charging control circuit of a paging receiver and a control method thereof for minimizing introduction of error during reception of data by differently controlling the operation of a quick charging circuit in response to a data transmission or reception state. The quick charging control circuit of a paging receiver having a battery, a radio frequency (RF) receiving circuit, a waveform shaping circuit with a charging circuit and a quick charging circuit includes preamble detecting and synchronization code detectors for respectively detecting a preamble signal and a synchronization code among data generated from the waveform-shaping circuit, a data processor for processing batch data among the data generated from the waveform-shaping circuit, and switch controller for providing the battery saving signal to the RF receiving circuit and waveform-shaping circuit and for providing the quick charge signal to the quick charging circuit by switching the voltage of the battery with a period of a first operating state for, detecting first and second predetermined codes, and controlling an output period of the battery saving signal and the quick charge signal with a second operating state for detecting a third predetermined code in response to outputs of the preamble and synchronization code detector.
