Abstract
A mobile communication device has a delay locked loop circuit for carrying out a tracking synchronization of a reception signal. The reception signal may be a spread spectrum signal. The delay locked loop circuit comprises a generating section for generating an early signal and first and second late signals which are different in phase from one another. A multiplying section is for multiplying the reception signal by each of the early signal and the first and the second late signals to produce first through third multiplied signals. A producing section produces an tracking error signal in accordance with the first through the third multiplied signals. A supplying section supplies a clock signal to the generating section on the basis of the tracking error signal to make the generating section generate the early signal and the first and the second late signals.
