摘要
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.关键词
