研究了电荷泵中电流源失配造成的假频分量 ,推导出了一个用于计算假频分量的公式 .提供了两个数表用于直观了解参数改变时假频变化情况 .最后对设计基于 DL L的 RF CMOS振荡器提供了一些参考方法
The aliasing component caused by the mismatch of the current source in the charge pump is studied and a formula for calculating the aliasing components is deduced.The two tables are provided for the intuitive understanding of the aliasing variation when the parameter is changed.Finally, The DL L RF CMOS Oscillator provides some reference methods
