Abstract :
A 2-6GHz broadband low-noise amplifier (LNA) with current reuse and noise-shaping technique is proposed for wideband matching, high power gain and flat noise figure (NF) response. The proposed UWB LNA is implemented in TSMC 0.18um CMOS technology. Measured results show that power gain is greater than 15dB and input return loss is larger than lOdB from 2 to 6GHz. The input third-order intercept point (IIP3) is -4dBm. Besides, a good noise figure of 3-3.7dB is obtained over the band of interest with a power dissipation of 15mW under a 1.8V power supply.
