Abstract—A fifth-order LPF with a quality factor tuning
circuit has been implemented for draft IEEE802.11n in a 0.13 m
CMOS technology. The proposed tuning technique realizes a
low-power 19.7 MHz, active-RC Chebyshev LPF. The filter has
2 dB gain, 30 nV/Hz1 2 input-referred noise, 113 dB V input
P1dB, draws 7.5 mA current from 1.5 V supply, and occupies an
area of 0.2 mm2.
