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

Abstract

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.
