Abstract :
A linear wideband low noise amplifier (LNA) that utilizes distortion canceling is proposed in this paper. It improves the linearity and contemporarily minimizes the effect of 2nd-order interaction. The deteriorating effect of the input matching network on the noise figure is also discussed. The proposed LNA designed in a 0.13mum standard RFCMOS technology, targets 3-5 GHZ UWB systems. The 3-dB bandwidth of LNA is 2.88 - 5.1 GHZ. The proposed LNA achieves a power gain of 11dB, better than 10 dB input matching, the minimum noise figure of 1.8 dB, and the input IP3 of +4.4 dBm, while dissipating only 5.2 mW from a single 1.2 V power supply.
