CMOS Low-Noise Amplifier for Mode-C & Mode-D MB-OFDM UWB Wireless Receiver

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 0.18 um RF CMOS process. Simulation results show that power gain of 12.4 dB, input and output matching lower then -8.5 dB and -14.5 dB, and a minimum NF of 4.0 dB can be achieved, while the power consumption is 11.2 mW through 1.8 V power supply.
