  • Patent number: 12283966
    Abstract: A Sigma Delta analog-to-digital converter (ADC) and a method for eliminating idle tones of the Sigma Delta ADC are provided. The Sigma Delta ADC includes a loop filter, a quantizer, an adder and a digital-to-analog converter (DAC). The loop filter performs filtering on a difference between an analog input signal and an analog feedback signal to generate a filtered signal. The quantizer is coupled to the loop filter, and generates a digital output signal according to the filtered signal. The adder is coupled to the quantizer, and adds a digital dithering signal to the digital output signal to generate a digital feedback signal. The DAC is coupled to the loop filter, and generates the analog feedback signal according to the digital feedback signal.

  • Patent number: 11223363
    Abstract: Disclosed is an open loop fractional frequency divider including an integer divider, a control circuit, and a phase interpolator. The integer divider processes an input clock according to the setting of a target frequency to generate a first frequency-divided clock and a second frequency-divided clock. The control circuit generates a coarse-tune control signal and a fine-tune control signal according to the setting. The phase interpolator generates an output clock according to the first frequency-divided clock, the second frequency-divided clock, and the two control signals. The two control signals are used for determining a first current, and their reversed signals are used for determining a second current. The phase interpolator controls a contribution of the first (second) frequency-divided clock to the generation of the output clock according to the first (second) frequency-divided clock, the reversed signal of the first (second) frequency-divided clock, and the first (second) current.

  • Patent number: 8953541
    Abstract: Embodiments of the present invention disclose a method, user equipment, base station, and system for detecting sharing of a timing advance value, relate to the field of communications technologies, and solve a problem in the prior art that a normal service cannot be provided because a TA value cannot be shared between different uplink CCs. According to the embodiments of the present invention, the user equipment may determine, through a time offset between synchronization of downlink component carriers corresponding to uplink component carriers, that a too large time offset indicates that a same TA value cannot be shared; the base station may calculate a TA value directly through a dedicated preamble sequence, and then compares the TA value with a TA value of one of the component carriers, where a too large difference between the TA values indicates that a same TA value cannot be shared.
