Design of a 3.1–10.6 GHz noise-canceling CMOS UWB receiver front-end

This paper tackles the problem by presenting the design of a 3.1-10.6 GHz noise-canceling CMOS receiver front-end for MB-OFDM UWB. A single-in-differential-out low noise amplifier (LNA) is proposed to enable the use of double-balanced mixers, without the need for a separate wideband balun. Further, noise cancellation in combination with inductive series and shunt peaking techniques are exploited to extend the circuit bandwidth and to lower the noise figure (NF) over the entire UWB band. The proposed UWB receiver front-end design is implemented in a 0.13um CMOS technology.
