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-Ám 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.
