摘要

介绍了一种可用于软件无线电射频前端的可重构CMOS射频调谐器的设计、仿真和测量。由22位移位寄存器控制的0.13μm高Q CMOS变容管周期性放置在低损耗共面波导(CPW)传输线上，形成4-11GHz可重构调谐器。单片调谐器不使用任何MEMS器件来实现可重构性。

A reconfigurable MEMS-less CMOS tuner for software defined radio

Design, simulation and measurement of a reconfigurable CMOS RF tuner that can be utilized in the RF front-end of a software defined radio are presented. 0.13μm high Q CMOS varactors controlled by a 22bit shift register are placed periodically on a low loss Coplanar Waveguide (CPW) transmission line to form a 4-11GHz reconfigurable tuner. The monolithic tuner does not use any MEMS devices to achieve the reconfigurability.
