Abstract: A phase-difference detecting method is for detecting phase difference between a first signal and a second signal of the same frequency. First, generate a detection signal. Next, sample the detection signal respectively according to the first signal and the second signal to obtain a first sample value and a second sample value. Then, determine whether a determination condition that the first and the second sample values are respectively equal to the previous first and second sample values is satisfied. When the determination condition is unsatisfied for the first time, record a delay time of the detection signal as a first time. When the determination condition is unsatisfied for the second time, record a delay time of the detection signal as a second time. Obtain the phase difference between the first signal and the second signal according to the first time and the second time.

Only three clocks are used in the digital circuit without involving all the oversampling clock phases to make the design timing complicated and critical. The system and method provide a simple clock structure to implement the digital circuit of high speed clock/data recovery in a robust and easy way. Furthermore a phase selection mechanism which decides the clock phase of the high speed data is provided as well.

Abstract: A training method of a digital-analog converter is provided. The digital-analog converter comprises a plurality of parallel capacitors, each of which is floatingly coupled to a plurality of correcting capacitors. Two voltages outputted from the digital-analog converter are received and compared. When a latter output voltage is lower than or equal to a former output voltage, the correcting capacitor is used to correct the capacitor corresponding to the latter output voltage until the latter output voltage is higher than the former output voltage. When the latter output voltage is higher than the former output voltage, a new voltage is outputted from the digital-analog convert and compared with the latter output voltage. The steps of comparing and correcting are repeated until every latter output voltage is higher than every former output voltage.

Abstract: A motor drive circuit and method with frequency setting and correcting functions. The drive circuit includes a speed control device, which simultaneously receives a sense signal and a rotation frequency signal. A pulse width modulation signal capable of modulating a duty ratio may be generated by a pulse width modulation method. The pulse width modulation signal is then transferred to a drive timing controller that generates a timing control signal to control output timing of a power drive signal for the drive circuit. Meanwhile, a sensor is used to detect a motor and to generate a correction sense signal, which is immediately fed back to the speed control device to form a closed loop control, so that the rotation frequency of the motor may be automatically corrected and set.
