Abstract

This paper describes a CMOS low-noise amplifier (LNA) and mixer intended for use in the front-end of a global positioning system (GPS) receiver. The circuits were implemented in a standard 0.35-μm (drawn) CMOS process, with one poly and two metal layers. The LNA has a forward gain (S21) of 17 dB and a noise figure of 3.8 dB. The mixer has a voltage conversion gain of -3.6 dB and a third-order intermodulation intercept point (IP3) of 10 dBm, input referred. The combination draws 12 mW from a 1.5-V supply
