Patent abstract

A phase-locked loop (PLL) is disclosed. One embodiment, among others, includes a PLL that provides a control current and varies the control current in proportion to an inverse of N squared. N is the ratio of the output frequency of the PLL system to the reference frequency of the PLL system. The varying of the control current compensates for bandwidth changes of the PLL system.
