    A 240MHz 5th-order gm-C low-pass filter for WiMedia UWB system is presented. The filter uses a 1.2V supply and is fabricated in 0.13μm CMOS. The filter is targeted for a direct-conversion radio receiver and is based on precise-gain filter synthesis. It includes gain control from 13 to 48dB in 1dB steps. The filter achieves an input-referred noise of 7.7nV/√Hz, an out-of-band IIP3 of -8.2dBV and consumes 24mW.
