| Abstract: | In this paper,we present the design of an integrated low noise amplifier(LNA)for wireless local area network(WLAN)applications in the 5.15-5.825 GHz range using a SiGe BiCMOS technology.A novel method that can determine both the optimum bias point and the frequency point for achieving the minimum noise figure is put forward.The method can be used to determine the optimum impedance over a relevant wider operating frequency range.The results show that this kind of optimizing method is more suitable for the WL... |
