  • Abstract
    A fifth order LPF with a quality factor(Q) tuning circuit has been implemented for IEEE802.11 n in a 0.13 mum CMOS technology. The proposed Q tuning technique enables a 19.7 MHz, active-RC Chebyshev LPF. The filter has 2 dB gain, 30 nV/Hz1/2 input referred noise, 113 dB muV input PIdB, draws 7.5 mA current from 1.5 V supply and occupies an area of 0.2 mm2.
