A FULLY INTEGRATED MULTIBAND CMOS 0.35 mu M LNA FOR IEEE802.16 STANDARD
In this paper we present the design of a fully integrated low noise amplifier for WiMAX standard with AMS 0.35 mu m CMOS process. This LNA is designed to cover the frequency range for licensed and unlicensed bands of the WiMAX 2.3-5.9 GHz. The proposed amplifier achieves a wide band input and output matching with S-11 and S-22 lower than -10 dB, a at gain of 12 dB and a noise figure around 3.5 dB for the entire band and from the upper to the higher frequencies. The presented wide band LNA employs a Chebyshev filter for input matching and an inductive shunt feedback for output matching with a bias current of 15mA and a supply voltage of 2.5 V.
