摘要：
In this paper, a high, flat gain and low noise factor for a 3-11 GHz single ended ultra-wideband low noise amplifier (LNA) applications. The proposed LNA uses current reuse technique for low power consumption, high and flat gain. To achieve wideband input matching, the shunt-shunt resistive feedback and degenerative parallel LC technique are used. The output matching is achieved by using cascaded LC technique. The proposed LNA dissipates 8.65 mW under supply voltage of 1.2 V, achieves the input reflection S11 below 10.61 dB, while the output reflection S22 below 11.28 dB, the gain S21 14.44-15.76 dB, and the noise figure NF 2.7-3.38 dB. This LNA is designed and simulated by a TSMC 0.18 mu m process.
