Abstract:
An apparatus and method are provided. The apparatus includes a phase locked loop (PLL) configured to generate a reference signal; a sub-sampling PLL (SS-PLL) connected to the PLL and configured to sub-sample the reference signal; and a first pre-charge circuit connected to a sampling device of the SS-PLL and configured to facilitate frequency locking of the SS-PLL.
