Phase-locked loops

A phase-locked loop (PLL) (101a) is disclosed. One embodiment, among others, includes a PLL that provides a control current (233) and varies the control current in proportion to an inverse of N squared. N is the ratio of the output frequency (216) of the PLL to the reference frequency (238) of the P...

Summary:A phase-locked loop (PLL) (101a) is disclosed. One embodiment, among others, includes a PLL that provides a control current (233) and varies the control current in proportion to an inverse of N squared. N is the ratio of the output frequency (216) of the PLL to the reference frequency (238) of the PLL. The varying of the control current compensates for bandwidth changes of the PLL.
