This paper presents a two-stage low noise amplifier (LNA) for 24 GHz automotive radar applications. Compared with traditional common source (CS) stage, the neutralized topology is used to improve the gain and reverse isolation in the first stage. In the second stage, an enhanced neutralized technique is adopted to improve the gain further. The LNA is fabricated by using standard 180-nm CMOS technology and occupies a chip area of 1.0 × 0.8 mm2. The design realizes a gain of 19.8 dB, a noise figure (NF) of 4.7 dB and an input 1 dB compression point (IP1dB) of −12 dBm.
