摘要

在简要介绍移相器应用的基础上，对不同实现方法进行了比较，提出了一种基于电流反射镜的全通可调移相技术，并在0.18um CMOS上进行了仿真。在新的电流模式方法中，晶体管的截止频率是所提出的移相器架构的工作极限，该设计的功耗为80微瓦。在HSpice中进行了仿真，覆盖了0.1GHz到50 GHz的频率范围。

A novel CMOS all-pass tunable phase shifter

A new current mirror based all-pass, tunable phase shifting technique is proposed and simulated in 0.18um CMOS, after a brief introduction on phase shifter applications, and comparison between different implementation methods. In the new current-mode approach, cut-off frequency of transistor is the operational limit of the proposed phase-shifter architecture and power consumption for this design is 80 microwatts. Simulations are carried out in HSpice and cover a frequency range from 0.1GHz to 50 GHz.
