This paper describes the design topology of a ultra-low power low noise amplifier (LNA) for wireless sensor network (WSN) application. The proposed design of ultra-low power 2.4 GHz CMOS LNA is implemented using 0.13-μm Silterra technology. The LNA benefits of low power from forward body bias technique for first and second stages. Two stages are implemented in order to enhance the gain while obtaining low power consumption for overall circuit. The simulation results show that the total power consumed is only 0.45 mW at low supply voltage of 0.55 V. The power consumption is decreased about 36% as compared with the previous work. A gain of 15.1 dB, noise figure (NF) of 5.9 dB and input third order intercept point (IIP3) of -2 dBm are achieved. The input return loss (S11) and the output return loss (S22) is -17.6 dB and -12.3 dB, respectively. Meanwhile, the calculated figure of merit (FOM) is 7.19 mW-1.

This paper presents a 0.3 mW 2.4 GHz low-power low-noise amplifier (LNA) using a forward-body bias technique for a wireless sensor network. The proposed LNA is implemented using CMOS 0.13-µm Silterra technology. The forward-body bias technique with a cascode configuration has been adopted in order to obtain low power consumption. A low supply voltage of 0.5 V is used to optimize the trade-offs between the LNA performances. The post-layout simulation results indicate that a power consumption of 0.3 mW is achieved. The simulated input return loss (S11) is less than -17.71 dB while the output return loss (S22) is below -14.83 dB. Moreover, the gain (S21) of 9.86 dB, the noise figure (NF) of 5.11 dB and the input-referred third-order intercept point (IIP3) of -7.5 dBm at 2.4 GHz is obtained with the calculated figure of merit (FOM) of 4.64 (1/mW).
