摘要

提出了一种低压高q有源电感的二阶射频带通滤波器。在滤波器中，描述了一种可调谐高q CMOS有源电感器的设计技术，该电感器工作在宽射频波段。仿真结果表明，在1.8V电源下，采用0.25 um CMOS工艺的滤波器的中心频率可工作在1.60G ~ 2.45GHz频段，当fc≈2.45GHz时，质量因子可从30 ~ 200调整。

Wide Tuning Range of A CMOS RF Bandpass Filter For Wireless Applications

A 2ndorder RF bandpass filter with high-Q active inductor using low-voltage is presented. In the filter, a design technique for a tunable high-Q CMOS active inductor operating in the wide RF-band is described. Simulated performance is presented showing that the center frequency of filter using a 0.25-um CMOS process can be operated at the 1.60G∼2.45GHz frequency band under a 1.8V power supply and quality factor is adjusted from 30∼200 when fc≈2.45GHz.
