Abstract :
This paper proposes a novel wide-tunable CMOS low noise amplifier (LNA) using on-chip variable inductor. The proposed tunable LNA can be utilized for multi-band RF front-end of software defined radio (SDR) and realizes a handheld terminal to enable global roaming. The LNA achieves power gain (PG) of over 10dB at 1.7-3.2 GHz tuning range.
