Abstract

A fully integrated direct conversion tri-mode receiver compliant with Global Positioning System (GPS), GSM1800, and WCDMA is presented. The configurable receiver consists of a wide band low noise amplifier with an on-chip matching network, Gilbert-cell mixers, and dynamically reconfigurable gm-C base-band filters. The RF and analog locks occupy 2.28 mm² in 0.18 mum SiGe technology. The measurement results show noise figure as low as 3.2 dB for GPS and IIP3 of -18 dBm
