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.
采用0.15/spl mu/m CMOS技术的自动调谐1.9GHz图像抑制前端
1.9GHz前端由LNA、带自动频率和Q调谐电路的图像抑制陷波滤波器和下变频混频器组成。在0.15/spl mu/m CMOS工艺中实现,0.45mm/sup /前端实现5.4dB噪声系数,-12dBm IIP3, 1.5V电源消耗19mW。
