| Abstract: | In this paper, a current controlled oscillator（YTO ）is creatively introduced by means of traditional PLL structure to take the place of the traditional Voltage Controlled Oscillator （VCO）and successfully overcome the shortcoming of large wideband phase noise of VCO. And, a high resolution, wideband frequency synthesizer is designed and realized by using voltage to current conversion technology to control YTO. |
