This paper presents the design and performance analysis of low-noise and low-power 0.35 µm SiGe UWB amplifiers for 3.1-10.6 GHz radio receivers, which have been approved by the US Federal Communications Commission on Feb. 14, 2002. Particularly, commongate amplifiers show good characteristics that are controllable with a single current source. These amplifiers give typical gain of 10.2 dB, which is flat to within ±0.3 dB variation over 3.1-10.6 GHz. The noise figure achieved is about 5.1 dB and power dissipation is 5.6 mW under a power supply of ±1.5 V. The results stand high when compared to recently published figures.
