A novel tunable dual-band low noise amplifier for 868/915 MHz and 2.4 GHz Zigbee application by CMOS technology

摘要

A dual-band (868/915 MHz and 2.4 GHz) low noise amplifier for Zigbee applications is designed using 035-μm CMOS technology. At 868/915 MHz and 2.4 GHz, the gains achieved are both 16 dB and the resulting noise figures are about 2.5 dB and 2.7 dB, respectively. The input and the output reflections are below-10 dB in both bands. The amplifier works at 2.5 V supply voltage with 12 mA current dissipation.
