• A Q-enhanced 8th order CMOS active bandpass filter is presented employing a novel two-stage self-calibration technique. The proposed active filter shows the better out-band attenuation performance than other reported CMOS active bandpass filters. The proposed calibration method enables the stable filtering operation affected by neither the input power variation nor the strong interference power. It is fabricated using 65nm CMOS process. The measured 3dB bandwidth is 54MHz at 2.37GHz. The insertion loss is 2.9dB and the out-band attenuation is 27.5dB at 15MHz offset frequency. The performance of the filter remains unchanged for ±5% supply voltage variations.
