description In this paper, we present a modified topology to reduce influence degree of the device parameters on the circuit performances. In addition, the larger VCO gain (KVCO) brings about the worse phase noise [2]. Hence, the topology of switching capacitor is used to enhance the characteristics of phase noise by dividing the wanted frequency band into four sections.
