Abstract

A sub-mW low-noise amplifier (LNA) is designed and implemented using a 0.18 μm CMOS standard process for wireless sensor network (WSN) applications. An important goal of the design is to achieve the low noise figure (NF) that is required in WSN receivers with low power consumption (P_DC). The forward body bias technique is used to reduce power consumption of the LNA. A supply voltage of 0.6 V is used with a power consumption of 0.84 mW. The LNA operated at 2.4 GHz achieves a NF of 2.88 dB and a gain of 10.1 dB.
