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.
