摘要

本文以微波180nm CMOS技术为例，研究了基于RC和RLC结构的矢量调制移相器正交成形器的两种主要实现方法。根据CMOS的平衡特性，解释了不平衡输入结构的选择。相位和幅度误差比较，以及输入匹配。最后，总结了所考虑的Alter结构的主要优点和缺点，并证明RC结构是最小相位误差移相器的较好选择。

Comparative analysis of RC- and RLC-complex filters for microwave microelectronic phaseshifters

In this paper two main approaches to the realization of vector-modulation phase shifters quadrature formers based on RC and RLC structures are considered for the case of microwave 180 nm CMOS technology. The choice of unbalanced input structure is explained due to CMOS balun characteristics. Phase and amplitude errors are compared, as well as input matching. In conclusion, main advantages and disadvantages of the considered Alter structures are summarized, with RC structure being proven as a better choice for minimum phase error phaseshifters.
