Abstract
A DECT/Bluetooth multi-standard front-end with adaptive image rejection is described. The front-end is designed and simulated in 0.18 µm CMOS technology. Using a multi-band LNA with zero external components full integration of the front-end is achieved. In high image-reject DECT mode it has a NF of 10 dB consuming a current of 47 mA, while in low image-reject DECT mode a NF of 5 dB is obtained with a current of 39 mA. In high image-reject Bluetooth mode the front-end achieves a NF of 10 dB consuming a current of 39 mA and in low image-reject Bluetooth mode it has a NF of 5 dB using a current of 31 mA. Applying adaptive image rejection the power consumption is reduced 20%, the NF is improved 50% and the gain improves 30%, while the chip area is negligibly increased compared to the total chip area occupied by the front-end.
