Abstract :
A fully integrated 1.9 GHz CMOS low-noise amplifer (LNA) has been implemented in a 0.8 μm CMOS technology. For low-noise performance, the amplifier employs high-quality spiral inductors with a duality factor of 8.5-12.5, and device layout and bias condition of the active devices were optimized for low-noise conditions. This amplifier showed a noise figure of 2.8 dB with a forward gain of 15 dB at current consumption of 15 mA. To the authors´ knowledge, this represents the lowest noise figure reported to date for a fully integrated CMOS LNA operating at 1.9 GHz.
