Abstract :

FM bandwidth Modulation is an important parameter in voltage-controlled oscillators. The importance of this parameter is especially evident in cases in which the loop bandwidth of phase locked loops is comparable with the FM bandwidth of the oscillator. In this paper, a practical method for measuring the FM bandwidth of a voltage-controlled oscillator is presented.
