This paper presents high-gain and low-noise 24GHz low noise amplifier(LNA) for automotive side and rear looking short range radar(SRR). The proposed circuit is designed using TSMC 0.13μm mixed signal/RF CMOS process(f T/fMAX =120/140GHz). To improve voltage gain of the amplifier, it has a 2-stage cascode structure. It uses transmission lines to reduce chip size and to improve input and output impedance matching. The radio frequency circuit and layout techniques are used to reduce parasitic capacitances at the radio frequency band of 24GHz. It showed low cost and low power dissipation since it is realized using CMOS process. The proposed low noise amplifier showed the highest voltage gain of 39dB, the lowest noise figure of 3.85dB, and the most excellent IIP3 of 2.5dBm as compared to recently reported research results.
