A switching-band CMOS low-noise amplifier for 6–11GHz MB-OFDM UWB wireless radio system

This paper presents a low-power low-noise amplifier (LNA) with switching bands for MB-OFDM Group-C and Group-D ultra-wideband wireless radio system. The LNA is designed and implemented in TSMC 0.18um RF CMOS process. Simulation results show that power gain of 12.4dB, input and output matching lower then ‒8.5dB and ‒14.5dB, and a minimum NF of 4.0dB can be achieved, while the power consumption is 11.2 mW through 1.8V power supply.
