Abstract

Low Noise Amplifier (LNA) is one of the essential components in Ultra Wideband (UWB) devices. Conventional LNA suffers from large chip area, high power consumption and inadequate Noise Figure (NF). A compact UWB LNA in the bandwidth of 3.1 to 10.6 GHz is proposed. The design is based on inductor-less configuration using the resistive shunt feedback topology and noise canceling techniques for wideband and high gain characteristics. Designed in 0.18-μm CMOS technology without applying any inductors and capacitors in the core circuit, the chip area is only 0.001 mm² and consumes 16.11 mW of power at 1.5-V supply. The maximum gain is 18.01 dB and the minimum NF noise is 1.324 dB.
