Abstract :
Requirements of Wireless Sensor Network application which are limited power, required energy and moderate performance has been forced the Wireless Sensor Network transceiver designers toward an adaptive transceiver structures. To address the above mentioned concerns, a low-noise amplifier integrated in 2.4 GHz, in 0.18 μm CMOS technology is developed. The proposed LNA can operate at 1.8 V supply voltage. The LNA provides a good gain of 17 dB, a noise figure of 0.01 dB, reverse isolation (S12) of -3 dB, input return loss (S11) of -15 dB and output return loss (S22) of -7 dB, while consuming only 7.2 Mw DC power.
