Low-power, low-voltage CMOS ultra-wideband low noise amplifier for portable devices

This paper presents the design of an ultra wideband low noise amplifier (UWB LNA). The proposed UWB LNA employs common gate and common source stages configured as a current reuse topology. The UWB LNA has a maximum gain of 14 dB with minimum NF of 3.0 dB. Good input and output impedance matching are achieved over the operating frequency band. The proposed UWB LNA consumes only 2.0 mW from a 0.9V power supply. This UWB LNA is designed and simulated in the standard 0.18 mu m CMOS technology.
