Abstract :
This paper presents the design of the matching network of a 60-GHz high-gain LNA. Through analyzing commonly used structure, a simplified input matching network was designed and an inter-stage matching network was proposed to improve gain and reduce noise. Simulated in 0.13-μm SiGe BiCMOS technology, the LNA provides a gain of 20 dB with a noise figure of 5 dB while consuming 3 mA from a 2.5-V supply.
