Abstract—In this paper, we present an ultra-low-power Low Noise Amplifier (LNA) for MedRadio band application. The LNA in this paper is known as differential cross-coupling common gate amplifier. The main structure of the design is the common gate configuration amplifier. A new technique such as cross-coupling technique is integrated to improve the gain and noise figure of the amplifier. The differential topology is finally implemented to improve the overall performance of the LNA. The final LNA is implemented in CMOS by using Silterra’s CMOS 180 nm technology. The LNA is designed with voltage supply equal to 1 V. The current consumption is equal to 0.2 mA. Therefore, the overall power consumption of the LNA is equal to 0.2 mW. Apart from this, the final simulated power gain for complete differential cross-coupling common gate amplifier is equal to 17.2 dB, and the simulated noise figure is equal to 5.4 dB. The designed LNA can operate from 80 MHz to 800 MHz. In addition, MOSCAPs are used to replace all the conventional passive capacitors in order to reduce the overall area of the LNA.
