摘要
提出了一种改进的基于差动有源电感的射频带通滤波器的调谐方法。基于先前设计的纯晶体管二阶滤波器拓扑，在0.18 μ m CMOS技术中证明了独立的频率和质量因子调谐。该电路基本上是为2.4 GHz设计的，这个频率高到足以覆盖主要的无线标准，功耗小，Q值也很高。使用on可获得较宽的频率调谐范围。芯片变容器。该电路从2.4 GHz中心频率的1.8 V电源中吸收1mw。
Active RF bandpass filter with wide frequency tuning range
The paper presents an improved tuning method implemented for a differential active inductor based RF bandpass filter. Derived from a previous designed transistor-only second order filter topology, independent frequency and quality factor tuning are demonstrated in 0.18 mum CMOS technology. The circuit has been basically designed for 2.4 GHz, a frequency high enough to cover the main wireless standards, has small power consumption and can exhibit very high Q values. A wide frequency tuning range is obtained by using on.chip varactors. The circuit absorbs 1 mW from a 1.8 V supply at 2.4 GHz central frequency.
