  • Publication number: 20250088343
    Abstract: In a PLL, a VCO is controlled by a control voltage and produces an output periodic signal. A comparator compares the control voltage to a comparison signal, and asserts/de-asserts a detection signal if the control voltage is higher/lower than the comparison signal. A digital logic circuit receives the detection signal, produces the comparison signal, and produces a compensation signal to control the VCO. During a VCO compensation procedure first phase, the digital logic circuit determines and stores a value of the comparison signal that corresponds to a current value of the control voltage, and compares the stored value of the comparison signal to a target value to determine whether the control voltage needs to be increased or decreased. During a VCO compensation procedure second phase, the digital logic circuit iteratively changes the value of the compensation signal until the control voltage reaches a desired value.

  • Patent number: 12088310
    Abstract: A voltage-controlled oscillator in a phase-locked loop circuit is calibrated via a dichotomous search in a set of candidate frequency bands via a sequence of subsequent halving steps that produce reduced subsets of the set of candidate frequency bands. The reduced subsets have respective upper bound values and lower bound values, as well as central values. The central value of the subset resulting from the halving step of index i in the sequence is a function of the average of the upper bound value and the lower bound value of the subset resulting from the halving step of index i?1 in the sequence.
