Description
Summary:This work presents a 2.4 GHz low noise amplifier (LNA) for wireless sensor network in CMOS 0.13- mu m Silterra process. The forward body bias technique with cascode configuration has been adopted in order to implement a suitable LNA for low power consumption target. The supply voltage was varied from 0.4 V to 0.6 V as to optimize the tradeoffs for LNA performances. The simulation results show that the power consumption of 0.2 mW is achieved. However, the best performance of the proposed LNA is obtained at supply voltage of 0.5 V due to the tradeoffs between power consumption, s-parameters, noise figure (NF) and linearity. A gain of 12.03 dB, NF of 4.95 dB and input third order intercept point (IIP3) of -7.5 dBm at 2.4 GHz is obtained. The input return loss (S11) and the output return loss (S22) is below than -10 dB with the calculated figure of merit (FOM) is 6.46 (1/mW).
