Abstract :
A dual-loop frequency synthesizer topology using a wideband primary loop and programmable reference loop is analyzed and simulated. This architecture offers improved noise performance when compared with conventional designs. The IC compatible dual-loop design uses phase/frequency translation rather than frequency division
