Abstract :
This paper presents a fully-integrated CMOS front-end based on a direct conversion architecture for UMTS/802.11b-g and a low-IF at 100kHz for DCS 1800. The two key building blocks are a multi-band low noise amplifier that uses positive feedback to improve its gain and a highly linear mixer. The front-end, integrated in 0.13μm CMOS process, exhibits a minimum noise figure of 5.2dB, a programmable gain that can be varied from 13.5dB to 28.5dB, an IIP3 of more than -7.5dBm and an IIP2 better than 50dBm. The total current consumption is 20mA from a 1.2 V supply.
