Abstract :
A 1.9GHz front-end consists of an LNA, an image-reject notch filter with automatic frequency and Q tuning circuits, and a down-conversion mixer. Implemented in a 0.15/spl mu/m CMOS process, the 0.45mm/sup 2/ front-end achieves 5.4dB noise figure, -12dBm IIP3 and consumes 19mW from 1.5V supply.
