Abstract

This paper presents a design of 2.4 GHz low noise amplifier (LNA) for wireless sensor network (WSN) applications using CMOS 0.13 µm Silterra process. The proposed LNA employs a self-biased inverter to obtain high gain and able to operate at low supply voltage. The simulation results indicated that the proposed LNA achieves an input return loss (S11) of -37.7 dB, output return loss (S22) of -28.1 dB and gain of 10.5 dB. Moreover, the noise figure (NF) of 5.4 dB and the input third order intercept point (IIP3) of -10 dBm is obtained at 0.9 V supply voltage. The chip area is 0.49 mm2.
