In this paper, a low power and high gain low-noise amplifier (LNA) is presented for 24 GHz FMCW radar applications fabricated in a 0.18 mu m RF CMOS process. The proposed LNA is with the characteristics of the source inductive degeneration type, the current reuse technique, and the invariance of current density in CMOS process. The proposed LNA with a compact size has a gain of 18.95 dB and a noise figure of 5.8 dB, while consuming 11.3 mW. The measured input 1-dB compression point (IP1 dB) and an input third-order intercept point (IIP3) are -26 dBm and -16.5 dBm, respectively.
