Abstract: A method for automatically calibrating a phase locked loop (PLL) system includes estimating a frequency value of an input signal applied to the system. Based on the estimated frequency value, a driving signal is generated for a plurality of internal switches in the PLL system. A PLL system may also implement this automatic calibration method.
