A CMOS low noise amplifier (LNA) for low-power ultra-wideband (UWB) wireless applications is presented. To achieve low power consumption and wide operating bandwidth, the proposed LNA employing stagger tuning technique consists of two stacked common-source stages with different resonant frequencies. This work is implemented in 0.18-μm CMOS process and shows a 2.4-9.4-GHz bandwidth. The amplifier provides a maximum forward gain (821) of 10.9 dB while drawing 7.1 mW from a 1.8-V supply. A noise figure as low as 4.1 dB and an IIP3 of -3.5 dBm have been demonstrated.
