深入分析了最近提出的一种基于差动非线性传输线的二分频分频器，其作用类似于反射式分布谐振器。单细胞的翻转分叉轨迹是解析得到的，这使得我们能够理解分割器的行为并初步估计其元素值。论证了通过适当选择一个附加的线性电容器来改变分频阈值和带宽的可能性。还研究了单元数对分割带宽和亚谐频率处产生的驻波的影响。该技术已应用于输入频率为1.5 GHz和2.2 GHz的两个分频器。
A recently proposed frequency divider by two, based on differential nonlinear transmission line, acting like a reflective distributed resonator, is analyzed in-depth. The flip bifurcation locus of a single cell is obtained analytically, which enables an understanding of the divider behavior and an initial estimation of its element values. The possibility to modify the division threshold and bandwidth through the proper selection of an additional linear capacitor is demonstrated. The influence of the number of cells on the division bandwidth and on the generated standing wave at the subharmonic frequency is also investigated. The techniques have been applied to two frequency divider with 1.5 and 2.2 GHz input frequency.
