Popis:	A dual-feedback topology to extend bandwidth of resistive feedback LNAs is proposed in this paper. Active source follower shunt-shunt feedback using a shunt peaking inductor to extend the 3-dB and input matching bandwidth is employed, combined with series-shunt feedback for extended impedance matching using a source inductor. A prototype in 90nm digital CMOS achieves a high 3-dB bandwidth of 29GHz while preserving adequate input matching up to 22GHz. The miniature area (0.017 mm2) and low power consumption (8.4mW) make the solution very attractive for low-cost very wideband LNA implementation.
