LNA is one very essential bloc in the RF receiver. Due to the growth of the standard evolution, this component must handle several frequency bands with the best performances. This chapter presents a wide band LNA design for IEEE802.16 standard with the CMOS 0.35µm technology. In this LNA, we use a CPW transmission line to design the inductive degeneration inductor of 0.38nH. This circuit has a S21 of 12dB, a noise figure less than 3dB and an input/output reflexion coefficient less than -10dB between 2 and 6GHz. The CPW line presents a characteristic impedance of 120O, an inductance of 0.38nH, a capacitance of few fF and a resistance less than 2O on the desired frequency band.
