A 0.13/spl mu/m CMOS LNA with Integrated Balun and Notch Filter for 3-to-5GHz UWB Receivers

A 0.13mum CM0S LNA for 3-to-5GHz UWB receivers embedding an integrated balun is reported. The LNA includes an integrated notch filter to mitigate the interference of WLAN blockers both in the UNII and ISM bands. Measured performance includes: voltage gain of 19.4dB, S11 < -10dB over the entire band, P1dB > -9.4dBm, and maximum notch filter attenuation of 44dB. The LNA and the notch filter consume 24mW and 7.5mW, respectively.
