Abstract :
A new frequency detector, which allows for a fast frequency lock of phase-locked loops (PLLs), is presented. It uses the feedback divider that already exists in a PLL to determine the frequency difference. The proposed frequency detector provides frequency difference information at each reference cycle, and thus guarantees fast frequency acquisition
