An Accurate Automatic Quality-Factor Tuning Scheme for Second-Order LC Filters

This paper presents a scheme to accurately tune the quality factor of second-order LC bandpass filters. The information of the magnitude response at the center and one of the cutoff frequencies is used to tune both the amplitude and the quality factor of the filter using two independent yet interact...
