Abstract
An improved frequency synthesizer utilizes a first order loop and sample-and-hold phase detector with optimized gain to obtain very fast frequency locking characteristics. In addition, synchronization of the programming of the loop divider and of the range shifting the voltage controlled oscillator is also utilized. An adaptive loop filter is provided to allow a first order loop to be used for lock acquisition and still maintain excellent noise performance after lock has been obtained.
