In recent years, there has been an increasing interest in using Ultra WideBand (UWB) technology for short-range wireless communication interfaces. The IEEE 802.15.4a standard has adopted UWB as one of the interfaces for robust low-data-rate transmission in Wireless Personal Area Networks (WPANs) with precision ranging capabilities. Ultra WideBand (UWB) radio technology has inherent characteristics that make it highly suitable for low power applications. This paper shows the design of a Low Noise Amplifier (LNA) for 3.5-4.5GHz UWB frequency range. The proposed LNA consists of three stages, a cascode LNA an inductive inter-stage network and a common source amplifier with a shunt feedback resistor.
