Abstract :
The linear model of phase-locked loop with triple active RC notch filters (ARCN) which is proper for investigating of dynamic properties in the time domain and frequency domain are presented in this contribution. Also the noise analysis and noise optimization of such filters were carried out. Spectral properties and phase noise measurement on experimentally evaluated frequency synthesizer were carried out. Based on numerical simulations results has been possible to design good ARCN filters.
