Abstract(in English) | An UWB RF system can be used in the area of signal processing. The phase-noise of output voltage of the oscillator with Phase Locked Loop (PLL) should be suppressed for the performance. The low phase-noise characteristics as well as the broadband and high-frequency use are very important factor for the UWB application. In order to develop a low phase-noise PLL, we newly attempt to establish a method for designing the phase comparator with high sensitivity. A phase comparator is consisted of XOR with CMOS transistor. The W/L ratio related to the delay of CMOS transistor in the phase comparator was designed to improve the sensitivity. It was demonstrated by circuit simulation that the proposed phase comparator is effective in improving phase-noise of the PLL. This study reveals the basic considerations for low phase-noise PLL. |
