A +22dBm IIP3 and 3.5dB NF wideband receiver with RF and baseband blocker filtering techniques Conference Paper uri icon

abstract

  • The real challenge in designing wide-band receivers is the ability to tolerate out of band blockers. In this paper, different blocker rejection techniques are proposed to significantly improve the linearity. The blockers are first rejected prior to the LNA, then, a novel base-band blocker filtering technique further rejects the blockers at the TIA input. A dual mixer architecture is also employed to further attenuate blockers. Finally, a very low impedance TIA is designed to improve the linearity of the entire receiver chain. The receiver has an IIP3 of +22 dBm and a NF of 3.5 dB in 0.18 m CMOS technology. 2014 IEEE.
