Design of micro power CMOS LNA for healthcare applications

The need for radio frequency (RF) integrated circuits with low power consumption is increasing in wearable devices in healthcare applications. In this paper, it is proposed to design a Low Noise Amplifier (LNA) at 2.4GHz using TSMC 0.13μm CMOS process for RF receiver front-end for ultra low power consumption. Simulation results show 15 dB gain, -13dB return loss, 3.6 dB Noise Figure and -24 dBm input 1 dB compression point while consuming 800μW power at a supply voltage of 0.8V. The proposed LNA design saves power, area and cost.
