Patent ID: 6954109

Claim:
A phase-locked loop structure providing local oscillator signals for a multimode system, said phase-locked loop structure comprising: a first phase-locked loop including a first voltage controlled oscillator; a second phase-locked loop including a second voltage controlled oscillator; a first local oscillator output for providing a first local oscillator signal for at least one of said modes, wherein a signal output by said first voltage controlled oscillator is forwarded to said first local oscillator output; a second local oscillator output for providing a second local oscillator signal for a selectable one of said modes; and a selection component for forwarding a signal output by said first voltage controlled oscillator or a signal output by said second voltage controlled oscillator to said second local oscillator output, said selection component being arranged for forwarding to said second local oscillator output a signal which is output by the voltage controlled oscillator having a lower current consumption, whenever said signal is able to fulfill system requirements on said second local oscillator signal for a currently selected one of said modes.
