In this paper we present the design of a low noise amplifier for WiMAX (802.16a) standard with AMS 0.35μm CMOS process. This LNA is designed to cover the frequency range for licensed and unlicensed bands of the WiMAX 2.3GHz–5.9GHz. The proposed amplifier achieve a wide band input and output matching with S11 and S22 lower than −10dB, a flat gain of 13db and a noise figure between 3dB for all the band and from the upper to the higher frequencies. The presented wide band LNA employs a Chebychev filter for input matching and an inductive shunt feedback for output matching with a bias current of 25mA and a supply voltage of 2.5V.
