| 摘 要： | 提出了一种使用品质因数增强型的有源电感的射频带通滤波器,描述了在宽射频频段上可调谐的品质因数增强型的有源电感设计技术,而且解释了与有源电感噪声和稳定性相关的问题.该滤波器采用0.18μm CMOS工艺制造,它所占用芯片的有效面积仅为150μm×200μm.测试结果表明:该射频滤波器中心频率为2.44GHz时,3dB带宽为60MHz,中心频率可在2.07～2.44GHz范围内调谐,1dB压缩点为-15dBm,而静态功耗为10.8mW;在中心频率为2.07GHz时,滤波器的品质因数可达到103.

| Abstract: | An RF bandpass filter with a Q-enhancement active inductor is presented.The design technique for a tunable Q-enhancement CMOS active inductor operating in the wide RF-band is described.Moreover,issues related to noise and stability of the active inductor are explained.The filter was fabricated in 0.18μm CMOS technology,and the circuit occupied an active area of only 150μm×200μm.Measurement results show that the filter centered at 2.44GHz with about 60MHz bandwidth(3dB)is tunable in center frequency from about 2.07 to 2.44GHz.The 1dB compression point is -15dBm while consuming 10.8mW of DC power,and a maximum quality factor of 103 is attained at the center frequency of 2.07GHz. |
