Abstract :
This paper presents the design of a low-noise amplifier (LNA) targeted for ultra-wideband (UWB) applications. The design consists of two gain stages in multiple feedback loops to achieve broadband gain together with low noise figure and good input impedance match. Implemented with a 0.25μm SiGe BiCMOS process and housed in a standard LPCC package, the LNA chip gives 18.5 dB gain and 10.3GHz - 3 dB bandwidth (2.7 - 13 GHz) while consuming less than 19 mW of dc power through a 3 V supply. Over the 3.1 - 10.6 GHz UWB frequency band allocated by the FCC, noise figure of 2.1 - 3.3 dB and input return loss greater than 12.5 dB have been achieved.
