Abstract Absrrucr-In a PLL frequency synthesizer, the reference and VCO frequencies are divided down to their greatest common divisor frequency prior to phase comparison. We replace the dividers by a simplified form of digital frequency synthesizer, and examine the spectrum of the phase comparator outputs to show that the loop bandwidth can be dramatically increased, thereby improving the pull-in range and acquisition time. f,=K,f, I T
