| Abstract: | Based on the basic structure of the mirror current source circuit,an improved common source of supply current sources has been proposed and applied to the 1.8GHz of the VCO,the relation of the oscillation frequency of the VCO and the current source has been researched,a simulation is conduct in the Hspice as TSMC 0.25μm technology base,so that the size of MOS and static index of the current source are determined,the simulation shows the basic requirements of VCO has been achieved. |
