Abstract :
This paper presents a low-noise amplifier (LNA) with switching groups for MB-OFDM Group-A, C, 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 ll.ldB, input and output matching lower then -8.4 dB and -8.3 dB, and a minimum NF of 3.8 dB can be achieved, while the power consumption is 24.8 mW through 1.8 V power supply.
