Abstract

This paper presents a technique using current-mode approach for a CMOS differential low noise amplifier design, simulated with a TSMC 0.18 Â¿m RF CMOS process, working at 1.2 V supply. A comparison with conventional voltage-mode LNA shows that this LNA has advantages of low voltage, low power consumption and simple structure. Simulation results demonstrate that at 2.4 GHz, the noise figure is only 1.47 dB, transconductance gain is 12.63 dB, S11 is -26.47 dB, S22 is -23.64 dB. With voltage of 1.2 V, the power consumption is 6.49 mW.
