Abstract :
A frequency synthesizer employing a new digital frequency measurement method in a feedback loop is described. The synthesizer features high frequency resolution and a high operating frequency. The mostly digital nature of the synthesizer and relaxed voltage controlled oscillator requirements also make the synthesizer suitable for integration. Models for the synthesizer are developed and experimental results from a prototype are given
