Abstract
A 1.5-GHz low noise amplifier (LNA), intended for use in a global
positioning system (GPS) receiver, has been implemented in a standard
0.6-μm CMOS process. The amplifier provides a forward gain (S21) of
22 dB with a noise figure of only 3.5 dB while drawing 30 mW from a 1.5
V supply. In this paper, we present a detailed analysis of the LNA
architecture, including a discussion on the effects of induced gate
noise in MOS devices
