New 1.6GHz 2 Stage CMOS LNA for GPS Applications

In GPS applications, the LNA is normally placed close to the antenna as the GPS signal received from the GPS satellite tends to be quite weak and needs the LNA to amplify it. This can be achieved by using either a one stage amplifier (about 15dB) or a two stage amplifier (27dB). Two stages increases the amplification capabilities but is often combined with the downside of increasing the noise figure and the power consumption. However, unlike othe...
