    摘要: The present invention provides a digital spread spectrum frequency synthesizer that comprises a noise-shaped quantizer, a divider and an adjustment means. The noise-shaped quantizer is used to quantize a period control word to a time-varying value. The divider is used for generating an output signal by means of dividing a reference signal by the time-varying value, the output signal feeding back to the noise-shaped quantizer so that the noise-shaped quantizer generates the time-varying value in response to the feedback output signal. The adjustment means is used to adjust the period control word by a period offset in response to the output clock. Accordingly, the frequency synthesizer of the present invention can provide a very precise frequency synthesizer featuring a precision spread spectrum clock and jitter stability as well.

    摘要: A level clamping control circuit and associated level clamping control method are provided. The level clamping control circuit includes a reference level estimator, a subtractor, a clamping computation circuit, a dithering circuit, and a digital-to-analog converter (DAC). The reference level estimator estimates a reference level of the input signal. The subtractor computes a difference between the reference level and a desired reference level to output a difference signal. The clamping computation circuit generates a first control value according to the difference signal. The dithering circuit dithers the first control value to alternately output a plurality of second control values. Finally, the DAC respectively utilizes the second control values to charge or discharge a capacitor to adjust the reference level of the input signal.
