CMOS Dual-Band Low-Noise Amplifier for World-Wide WiMedia Ultra-Wideband Wireless Personal Area Network System

Abstract

This paper presents a dual-band low-noise amplifier (DB-LNA) with switching band groups for WiMedia Ultra-Wideband. The LNA is designed and implemented in TSMC 0.18um RF CMOS technology. Measurement results show that the DB-LNA gives 6.1dB and 9.8dB power gain, and that input and output matching are lower than-9.3dB/-9.4dB (Group-1/Group-6) and-9.2dB/-11.7dB (Group-1/Group-6). A minimum noise figure is 5.0dB/5.1dB (Group-1/Group-6) while consuming 24.8mW (including buffer) through 1.8V supply voltage.
