摘要： A clock circuit is suitable for use in a timing circuit which provides time information according to a reference clock. The clock circuit includes a clock detector to detect whether or not an interruption of the reference clock occurs. When the interruption of the reference clock occurs, a clock interruption signal is issued as a reference whether or not to reset the timing circuit.

摘要： A signal processing system including a DAC, a comparing unit, and a control unit is provided. The DAC receives a digital input and generates an output voltage. The comparing unit receives the output voltage and compares the output voltage with a reference voltage to output an output value. The control unit receives the output value and accordingly generates the digital input in a manner of value mapping through firmware or software to calibrate the DAC. Furthermore, a self-calibration digital-to-analog converting method is also provided.

摘要： An oscillator and a control circuit thereof are provided. The control circuit is configured to control an oscillator to adjust the amplitude and the level of an oscillation signal. The control circuit includes a peak amplitude detector, an average voltage detector, and an oscillation controller. The peak amplitude detector is configured to detect the amplitude of the oscillation signal, so as to generate an amplitude value. The average voltage detector is configured to detect the direct current (DC) level of the oscillation signal, so as to generate an average value. The oscillation controller is configured to generate two power signals according to the amplitude value and the average value. The two power signals are provided to the oscillator, so that the oscillator adjusts the amplitude and DC level of the oscillation signal.
