Abstract
Abstract – A CMOS low-noise amplifier (LNA) and mixer for a GPS front end is described. At 1.586Ghz the LNA minimum noise figure (NF) is 2.8dB, input third order intercept point (IIP3) is 2.45dB and forward gain is 30dB. With a 1.573Ghz local oscillator (LO) and a 1.586Ghz RF input the mixer minimum NF is 6.1dB, IIP3 is 12dB and a conversion gain of-3dB. The LNA and mixer consume 58mW of power from a 1.8V supply. The active area of the LNA and mixer is 0.5mm X 0.4mm X 0.2 mm. The prototypes are to be fabricated in a 0.18-Pm CMOS process.
