Abstract
This paper presents the design of a bandpass filter using a CMOS floating active inductor with a quality factor of 14.7. By tuning the biasing current in the circuit we can tune the quality factor and the resonant frequency of the floating active inductor as well as bandpass filter. The power consumption of the bandpass filter is 3.72 mW with a supply voltage of 1.8 V. The 1 dB compression point and IIP3 are 26.3 dBm and 27.6 dBm respectively. The centre frequency of the filter is 635 MHz with a bandwidth of 8 MHz which can be used in the broadcasting applications. The noise figure of the filter is 0.16 dB. The filter is designed in UMC 180 nm mixed mode CMOS process.
