A 2.4-GHz low-noise amplifier (LNA) radio frequency integrated circuit is designed and implemented using the 18-mu m CMOS standard process for ZigBee applications. A solar panel with a regulator circuit directly converts solar power to the electrical power of the LNA. The forward body bias method is applied to reduce the power consumed by the LNA, as required to provide green energy. Measurements of the solar-powered 2.4-GHz LNA are made, revealing that the noise figure is 2.91 dB, the gain is 10.89 dB, and the input-referred third-order intercept point is 0 dBm. A voltage of 0.6 V is supplied to the LNA and the power consumption is then 1.08 mW.
