چکیده
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.

A systematic system-level design methodology for multiband–multistandard (MB–MS) wideband/reconfigurable CMOS receivers is presented. The methodology determines the specifications (noise figure (NF) and linearity) for each building block to minimize the overall power consumption. System-level simulations show that the gain variation of the LNA for various bands/standards is an important factor ...
