A 4.7-10.5-GHz Ultra-wideband CMOS LNA Using Inductive Inter-stage Bandwidth Enhancement Technique

In this paper, a new CMOS low noise amplifier (LNA) is designed using inductive interstage network for ultra- wideband (UWB) receiver in a standard TSMC 0.18μm CMOS technology. The Spectre simulations show that the proposed UWB LNA achieves a flat 3-dB gain bandwidth of 4.7GHz to 10.5GHz, a power gain of 12dB, a minimum noise figure of 3.9dB and a total power dissipation of 7.2mW from a 1.2V power supply.
