Abstract :
An ultra wideband low-noise amplifier (LNA) with shunt resistive-feedback is proposed for wideband input matching, broadband power gain and flat noise figure (NF) response. The proposed wideband LNA is implemented in TSMC 0.18 μm CMOS technology. Measured results show that power gain is greater than 6.8 dB and input return loss (S11) is below -7 dB from 3.1 to 10.6 GHz. The minimax input 3rd-order intercept point (IIP3) is about 10 dBm, and the NF ranges from 3 to 7.1 dB over the band of interest. The finished chip size is 0.56 mm2.
